What ion does oxygen form?
What is O²⁻?
Which group of elements is most likely to gain one electron?
What are halogens?
An atom with no overall charge because the number of protons equals electrons.

What is an electron?
How many electrons can fit in f subshell?
What is 14 electrons?
What is the name of the compound NaCl?
What is sodium chloride?
These elements are unreactive because they have full valence shells.

Which element is more reactive: sodium or neon, and why?
What is sodium, because it has one valence electron and wants to lose it?
