Chapter 8

Chapter 8. Bonding. What is a Bond?. A force that holds atoms together. Why? We will look at it in terms of energy . Bond energy: the energy required to break a bond. Why are compounds formed? Because it gives the system the lowest energy . Ionic Bonding.

Covalent Bonds! Yeah!

Covalent Bonds! Yeah!. Elements with high electronegativities (non-metals) will not give up electrons. Bonds are not formed by a transfer of electrons, they are formed by sharing electrons. Molecules are neutral groups of covalently bonded atoms
