When an atom loses an electron, it becomes a:

• positive ion
• negative ion
• neutral ion
• neutral atom

Atoms form ions in order to become

• isotopes
• stable
• metals
• nonmetals

Why do ionic bonds form?

• so the number of protons equals the number of electrons
• to fill the outermost energy level
• so an atom can become unstable
