Why do ionic bonds form?

• They share electrons

• The two anions have the same change, so they are attracted to each other

• The two cations have an opposite charge, so they are attracted to each other

• The cation and anion have opposite charges, and opposite charges attract.

What is electronegativity?

• The ability of an atom to attract protons

• The ability of an atom to attract electrons

• The ability of an atom to be large

• The ability of an atom to be a metal
