Ionic, Covalent, and Metallic Bonding

 Ionic Bonding- form electrical attractions between large numbers of anions and cations.   Anions and cations combine so the number of negative and positive charges is equal. They can't isolate individual compounds. They form crystalline solids - form a crystal lattice to minimize potential energy


Covalent bonding- the sharing of electrons. There are two different kinds, polar and nonpolar. Nonpolar convalents don't dissolve in water (electrons easily shared, an equal electrical charge distribution). Polar convalents dissolve in water and have unequal electron sharing that causes unequal electrical charge distribution.

Metallic Bonding- attraction between metal atoms that are delocalized & the surrounding electrons; the p and d orbitals are semi-vacant which allows for electron roaming. These bonds have high conductivity (both electric and thermal), they are usually solids that don't dissolve in water, have high luster, and they are malleable and ductile

The pictures below are in order of Ionic, Covalent, and Metallic.
