Haloxide
Haloxide is an element that doesn't exist in our universe but it could exist in some parallel universe. It was theorized by Mr. Alatekin in 2019. Unlike the other elements, Haloxide's subatomic particles include different quark systems (Anti-up, anti-up quarks, etc.).
oxide, hydroxide, haloxide... That's what we did come from.
