complete the table below to identify and name several covalent compounds.

1.

Chemical formula: CaBr2

Chemical name: calcium bromide (calcium has only one valence, so it isn't necceseraly to name it)

Cation: Ca^2+

Anion: Br^-

Chemical formula: NiO

Chemical name: Nickel(II) oxide

Cation: Ni^2+ (the name Nickel (ii) come from its valence)

Anion: O^2-

Chemical formula: Cd3N2 (notice that the addition of the valences of all elements is equal to zero because compounds are neutral, that is, 3*(2+) + 2*(3-) = 0)

Chemical name: Cadmium(II) nitride

2.

Chemical formula: SiI4

Chemical name: Silicon tetraiodide

Chemical formula: N2O (as it name states, 2 atoms of N and 1 atom of O)

Chemical name: dinitrogen monoxide

Chemical formula: P4O10 (it's actually composed by two molecules of P2O5)

Chemical name: Phosphorus pentoxide

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6
