Occurs between like atoms of a
metal in the free state.

10. Ionic Bonding
• Ionic compound results when a metal
reacts with a nonmetal.

11. Covalent Bonding
• A covalent bond
results when
electrons are shared
by nuclei.

12. Metallic bonding
Occurs between like atoms of a metal
in the free state.

13. Why do atoms bond with each
other to form a compound?

14. How to atoms bond with each
other to form compounds

15. What are the three types of
chemical bond?

16. Chemical Bonds
Three types:
Ionic Covalent Metallic

17. Chemical Bond
• Forces that hold groups of atoms together
and make them function as a unit.
