Electrons
5. Fluorine has _____ outer electrons.
7
6. What is the only element known to attack/react with glass?
Fluorine
7. Name at least one of the elements in the noble family (Nobel gases).

Coppers
12. Who does chlorine decide to bond with?
Sodium
13. Why is Uranium a bouncer at the under 18 party?
Because he is big
