118
Symbol: H
Student number: 001
Group: hydrogen
Category: gaseous non-metal
The oldest of all the students at Academy 118, although she doesn’t look like it. She’s usually friendly, upbeat, and optimistic, but she can be quite explosive at times, especially if you make fun of her height. She enjoys swimming, spending time in the sun, and hanging out with her best friends, Carbon, Nitrogen, and Oxygen.
Symbol: He
Student number: 002
Group: noble gases
Category: gaseous non-metal
The small, timid and easily bullied type. He’s constantly being terrorized by the heavy metals, who make fun of his squeaky voice, and he often wishes he could just float away.
Symbol: Li
Student number: 003
Group: alkali metals
Category: solid metal
A technology expert and child at heart. He loves building drones, remote-controlled cars, and toy guns, and his phone never seems to run out of battery.
Symbol: Be
Student number: 004
Group: alkaline earth metals
Category: solid metal
Beryllium might seem small and sweet, but she’s actually quite toxic. She likes wearing emeralds and aquamarine and is surprisingly strong for her size.
Symbol: B
Student number: 005
Group: boron group
Category: solid metalloid
A straight-laced, hardworking student who can be quite abrasive at times. He’s a bit obsessive about keeping things clean, and he’s heard way too many jokes about how his name sounds like "boring."
Symbol: C
Student number: 006
Group: carbon group
Category: solid non-metal
An multitalented, straight-A student who’s joined almost all the clubs at school. She suffers from dissociative identity disorder: usually in her Graphite form, she switches to her Diamond persona in bouts often triggered by stress. She has a number of rarer personalities as well.
An animal lover to the core, Carbon shares her dorm room not only with her best friend, Hydrogen, but also with her pets, including her cats Methane and Octane, her dog Acetylene, her rattlesnake Benzene, her hawk Acetone, and many, many more. When she’s not busy studying for the Universal Biology Olympiad, she enjoys gardening, writing, nature walks, and fizzy drinks.
Symbol: N
Student number: 007
Group: nitrogen group
Category: gaseous non-metal
A calm, cool introvert who collects model cars and rockets. He’s lost count of how many times he’s had to keep his best friend and roommate, Oxygen, out of trouble. His favourite season is winter and he loves snowboarding, skiing, and skating.
Symbol: O
Student number: 008
Group: oxygen group
Category: gaseous non-metal
An energetic, outgoing athlete who especially loves long-distance running and swimming. As the president of the Student Council, he’s super-popular and makes friends easily. He can be hotheaded and a bit of a troublemaker sometimes, but you just can't live without him. He has a strange liking for setting fires and once accidentally burned down the entire left wing of the school.
Symbol: F
Student number: 009
Group: halogens
Category: gaseous non-metal
A mean, corrosive student with a brilliant but venomous smile. She and her band of friends, including Chlorine, Beryllium, and Antimony, stalk the school grounds whispering and making catty remarks about the meeker girls. She’s the school’s biggest fan of the Electrons card game, always on the hunt for the rare 2P6 Electron so she can complete her second set.
Symbol: Ne
Student number: 010
Group: noble gases
Category: gaseous non-metal
Though Neon may dress in bright, flashy colours, she’s actually one of the shyest students at Academy 118. She loves her red highlights and glowing jewelry, but wishes they didn’t call so much attention to herself.
Symbol: Na
Student number: 011
Group: alkali metals
Category: solid metal
Like the rest of the alkalis, Sodium is often found hanging out with Chlorine and the other halogens, but isn’t quite as mean-spirited as them. He has good reflexes and enjoys ocean sports such as surfing. He loves eating chips, pretzels, beef jerky, and anything with salt on it. He gets angered quite easily.
Symbol: Mg
Student number: 012
Group: alkaline earth metals
Category: solid metal
A strong athlete and fast runner with a passion for auto racing. In his spare time, he likes going go-karting, playing racing video games, and relaxing with an Epsom salt bath.
Symbol: Al
Student number: 013
Group: boron group
Category: solid metal
An average-looking student who doesn’t call much attention to himself. His favourite subject is engineering and he loves building things, especially model airplanes. Although his speed and agility make him a great badminton player, he’s skinny and a bit weak and longs to be stronger. As a child, he was even richer than Gold, but he’s lost all his wealth since and hardly remembers that time. He prefers to be called “Aluminium” (with an ‘i’), but only a few people use that name.
Symbol: Si
Student number: 014
Group: carbon group
Category: solid metalloid
A gifted student with extremely high mathematical ability, Silicon is an expert problem solver who has brought home neckfuls of medals from international computing and math olympiads. She rarely needs pencil and paper and can do immense calculations in her head. She absolutely loves computer science, being the president of Academy 118’s CS and math clubs, and she once wrote a Piet interpreter in assembly just for fun. She can recite an arbitrary number of digits of pi because she hasn’t actually memorized any of the digits. She just calculates them on the spot. The only class she doesn’t get good grades in is biology—she’s never understood it.
Symbol: P
Student number: 015
Group: nitrogen group
Category: solid non-metal
A showy partygoer. Much like Oxygen, she’s very athletic and loves endurance sports. She enjoys lighting fireworks.
Symbol: S
Student number: 016
Group: oxygen group
Category: solid non-metal
The class clown whose sense of humour never matured past that of a ten-year-old. His idea of a good prank is sticking a whoopee cushion on someone’s chair, and he thinks fart jokes are hilarious. He’s really bad at cooking.
Symbol: Cl
Student number: 017
Group: halogens
Category: gaseous non-metal
A snarky student with bleach-blonde hair and a corrosive attitude. Like the rest of the halogens, she loves the Electrons card game. She’s the school’s star swimmer and spends most of her time near the pool. Her favourite colour is green.
Symbol: Ar
Student number: 018
Group: noble gases
Category: gaseous non-metal
An extremely introverted, emotionless loner who doesn’t care about anything other than books. Friends? Don’t care. Parties? Boring. Studying? Whatever. They get good grades without paying attention in class anyway, mainly because they’ve already read pretty much every textbook in existence. Unlike Helium and Neon, they’ve actually been dragged to parties a few times (usually by Hydrogen and Fluorine), which just intensifies their dislike for people.
They go by they/them, so respect their pronouns. Or don’t. Like they care.
Symbol: K
Student number: 019
Group: alkali metals
Category: solid metal
An energetic, reactive student much like the rest of the alkalis. He’s really into war history and collects miniature guns and cannons. His favourite food is the banana.

Category: solid metal
A tall student who loves to drink milk and wears lots of seashell jewelry. She enjoys sculpting and wants to become an architect.
Symbol: Sc
Student number: 021
Group: transition metals
Category: solid metal
The first student at Academy 118 that you probably haven’t heard of before. He plays on the school tennis and badminton teams, and although he’s just as good as Aluminum and rivals even the school’s star athlete Titanium, nobody ever seems to remember his name. He’s been described as “a metal that’s not very interesting,” which really annoys him.
Symbol: Ti
Student number: 022
Group: transition metals
Category: solid metal
Though she may not look like it, Titanium is actually the strongest student at Academy 118. Apart from her incredible strength, she also possesses enormous speed, agility, and endurance, making her the school’s best athlete. She loves all kinds of sports, but especially enjoys tennis, lacrosse, and cycling. She’s accidentally broken off quite a few doorknobs while trying to open doors that were locked. Anybody who dares to call her cute will quickly find themselves being picked up and thrown across the room, and all the bullies, even Uranium and Plutonium, fear her.
Symbol: V

An athletic student. She loves working with cars and aspires to be a mechanic.
Symbol: Cr

An artistic student who especially enjoys painting. She loves the colour blue and uses it in all of her works. Though she’s usually kind to others, she absolutely despises Platinum.
Symbol: Ni
Student number: 028
Group: transition metals
Category: solid metal
A noble metal wannabe. Despite being in the same group as super-wealthy Platinum, she’s very poor and has to get most of her jewelry and clothing at the thrift store. She longs for the luxurious life of a noble metal and will do anything for the opportunity to get rich, even buying into Arsenic’s scams. She always tries to hang around Sliver, Gold, and Platinum, who find her annoying and mainly use her to carry their bags and fetch things for them.
Symbol: Cu
Student number: 029
Group: transition metals
Category: solid metal
The first element to join the Academy. Copper loves engineering and robotics and could probably build a four-function calculator using only a pack of toothpicks. She has heavily modified her dorm room, with motion-detecting lights, a bed that retracts into the wall, and secret compartments in the closet. Although she’s in the same group as Silver and Gold and could pass for a noble metal just by her looks, she isn't stuck up like them. In her free time, she plays trumpet in the school band and enjoys eating crab. Her eyes are Statue of Liberty green.

She can’t stand hot weather, which often causes her to have meltdowns.
Symbol: Ge
Student number: 032
Group: carbon group
Category: solid metalloid
A computer science lover who used to be an even better programmer than Silicon, but has slipped quite a bit since.
Symbol: As
Student number: 033
Group: nitrogen group
Category: solid metalloid
A charming and highly intelligent con artist. His programming skills are on par with those of Silicon, which angers her immensely. His hacking career began in the first grade, when he deleted all of Academy 118’s student records through an SQL injection attack. The other heavy metals Lead and Mercury (which he calls “the two imbeciles”) look up to him and are always trying to help him with his schemes, but they usually just end up getting in the way. He occasionally works with Antimony, although the two will backstab each other given the chance. His favourite food is rice.
Symbol: Se

Once on almost equal grounds with Gold, Silver is now being overshadowed by him and Platinum; though she is still far more wealthy than the average student, the two regard her as being second to them. On a quest to regain her lost status, she’s become quite the expert in business and economics. Her complexion isn’t as naturally flawless as that of Platinum, who makes fun of her for it. She’s a good speaker and enjoys acting in her spare time. She also loves photography, filmmaking, playing the flute, and going to the movies.

The richest and bossiest of all the noble metals and their self-proclaimed leader. She's lost count of how many credit cards she owns, and her jewelry and clothing collections spill over into her roommate Silver’s side of the dorm, much to Silver’s annoyance. She looks down on all the other students, often calling them “cheap metals,” even those who are neither cheap nor metals. As a child, she was incredibly poor and was even called “Little Silver” as she was following Silver and Gold all the time, but she seems to have forgotten this now. In her spare time, she enjoys shopping in the highest-end stores and eating out at expensive restaurants. She finds her groupie Nickel extremely annoying.
