Why do all bonds form?
so the number of protons equals the number of electrons
so an atom can become unstable
to fill the outermost energy level

In an ionic bond, the ions are held together because...
the positive nucleus of each ion attracts the other ion's negatively charged electrons
the ions have opposite charges
as the electron moved from one atom to another it pulled the atom along with it
electrons are being shared
