Ionic bonding occurs when atoms transfer electrons, forming positive and negative ions that bond together. Specifically, metals donate electrons to nonmetals to complete their outer energy levels, with the metal always written first in the compound. The final bonded ionic compound is stable with no overall charge.

1. Ionic Bonding (1-2)

2. Bonding that involves a transfer of electrons is called ionic bonding . Both atoms wish to complete their outermost energy levels one atom gives up electrons (positive ion) & one atom takes in electrons (negative ion)

4. All Ionic bonds are bonding metal to nonmetal. Metals always donate e- Nonmetals always accept e- Metals are always written first. The final bonded compound must be stable with a total charge of 0
