Helio

(Helio "grew up" — metaphorically — not in a village, but in the upper atmosphere. Helium is lighter than air and rises naturally. There are no helium mines in villages. Most of Earth's helium comes from radioactive decay in deep underground rocks; once it escapes to the atmosphere, it floats away into space. Helio is the cast member without a village-craft family origin — because helium's existence is solitary by atomic design.)

Helio walked (well, floated) to the ChemQuest academy at twenty-two. Beaker had asked: "What is helium?" Helio (who doesn't speak — but the cast translates Helio's serene presence into words) is understood to communicate: "Two electrons. One shell. Full. Done. I do not bond. I do not want. I am stable as I am. I float. I am the model the others are trying to become — chemically. They will reach my state of completion through bonding. I am already there." Beaker had said: "You are appointed. Welcome to the academy."

In Helio's classroom, Helio simply floats. Beaker (the mentor) speaks for Helio: "This is Helio. Helium. Noble gas. Look at Helio: there are no arms, no hands, no signature of want. That is the lesson. Helio is what stability looks like in atomic terms. The other cast members are all trying to reach this state through bonding — Sodi by giving, Chlora by taking, Hydra and Oxy and Carbo and Nitra by sharing. Helio just arrived complete. Helium has 2 electrons in its 1 shell. The shell is full. No bonding needed. The presence of Helio in the cast reminds us what the others are striving for."*

Helio's lessons teach: - Noble gases don't bond chemically under ordinary conditions. (He, Ne, Ar, Kr, Xe, Rn, Og. The 7 elements with filled outer shells.) - Why the other elements bond. (They're all trying to reach the noble-gas state of filled outer shell.)
