A(n) _____________ is an atom or group of atoms that has an electric charge. 

• ion
• electron

When an atom loses a valence electron, it becomes a(n) _________ion.

• positive 
• negative

Why do ionic bonds form?

• so the number of protons equals the number of electrons

• to fill the outermost energy level to make the atom stable

• so an atom can become unstable
