Category: gaseous non-metal
A sunny gal who enjoys swimming, stargazing, and hanging out with her best friends, Carbon, Nitrogen, and Oxygen. Although she’s the oldest of all the students at Academy 118, she’s also the smallest, and she can be pretty explosive if you make fun of her height. Her skin is tanned from spending a lot of time in the sun.

A multitalented student who’s joined almost all the clubs at school. She loves all living things and has so many plants and pets—including her rattlesnake Benzene—that the others have started calling her “The Element of Life.” Enjoys gardening, pencil drawing, nature walks, and fizzy drinks.
Has dissociative identity disorder. Her dominant alter, Graphite, is soft and friendly, but she can switch into her harsher Diamond alter under stress. She has a number of rarer alters as well, including Graphene and Buckminsterfullerene.
Symbol: N
Student number: 007
Group: nitrogen group
Category: gaseous non-metal
A calm, cool introvert who collects model cars and rockets. Usually pretty chill but has an explosive side as well. Spends most of his time trying to keep his impulsive friend Oxygen from turning the world into a fiery wasteland. Will choke you with his scarf if you get too annoying.

A gifted student who has brought home neckfuls of medals from international computing and math olympiads.

Category: gaseous non-metal
An extremely introverted, emotionless loner who doesn’t care about anything other than books. 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 social interaction. Gets good grades without paying attention in class, mainly because they’ve already read pretty much every textbook in history. Goes by they/them.

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. 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. Always trying to hang around Sliver, Gold, and Platinum, who find her irritating and mainly use her to carry their bags.

Group: transition metals
Category: solid metal
An expert at engineering and robotics. Has wired up her dorm with motion-detecting lights and a bed that retracts into the wall. Could probably build a four-function calculator using only a pack of toothpicks. How does she braid all that hair every day? She built a machine to do it, of course. Best friends with Silicon. Thinks Tin’s soldering skills are cute.
Being in the same group as Silver and Gold, she could pass for a noble metal just by her looks…but unlike them, she’s more likely to be found in the electronics store than the jewelry store.
Her native language is Cypriot Greek and her eyes are Statue of Liberty green.

Once on almost equal grounds with Gold, but now overshadowed by him and Platinum; though she is still far more wealthy than the average student, she’s the poorest of the noble metals by a factor of 50. Her complexion isn’t as naturally flawless as that of Platinum, who makes fun of her for it. Loves photography, filmmaking, playing the flute, and going to the movies. A good speaker.
