Apply: Atoms are most stable when their outermost shell is full. If their outermost shell is not full, atoms tend to gain, lose, or share electrons until the shell fills up. While doing
this, atoms react and form chemical bonds with other atoms.
Based on this, what can you infer about the reactivity of helium and neon?
O Helium and neon have full outer shells, so they are ready to start a new shell to form
chemical bonds.
Helium and neon have full outer shells, so they won't react to form chemical bonds.
Helium and neon have full outer shells, so they will react with anything to form chemical
bonds.
