Answer:
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
