Ionic Bonding

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
