Review the types of elements that create ionic bonds as

well as the types of elements that create covalent bonds.

• N2 • CCl4 • SiO2

• AlCl3 • CaCl2 • LiBr

N2 Covalent

CCl4 Covalent

SiO2 Covalent

AlCl3 Covalent

CaCl2 Ionic

LiBr Covalent

Explanation:

With covalent bonds, there is a sharing of electron pairs between the atoms.

With ionic bonds, there is complete transfer of valence electrons between atoms. Formed by the interaction of a metal with a non-metal.

Where:

Electrons aren't transferred in covalent bonds.

Protons aren't transferred in covalent bonds

Protons aren't shared in covalent bonds

N3-

C4+

Cl-

Si4 + = Metal

O2 - = Non-metal

Al3 + = Metal

Li + = Metal

Ca2 + = Metal

Br 1-, 1+, 5 + = Halogen

N2 = N3 - and N3 - Covalent

CCl4 = C4 + and Cl - x4 Covalent

SiO2 = Si4 + and O2 - x 2 Metal with non metal Covalent

AlCl3 = Al3 + and Cl - x 3 Covalent Though this one is complex as to why because it seems like it should be ionic

CaCl2 = Ca2 + and Cl - x 2 Metal with non-metal Ionic

LiBr = Li + and Br - Covalent as neither is a non-metal
