Gr. 10 Chem: Naming Molecular Compounds

What are Molecular compounds?

-Compound that is composed of 2 non-metals

-Electrons are shared between the non-metals

What are the 3 ways non-metals can share electrons?

1. Single bond (-)

   2 e- shared = 1 pair of e-

2. Double bond (2 dashes stacked)

   4 e- shared = 2 pairs of e-

3. Triple bond (3 dashes stacked)

   6 e- shared = 3 pairs of e-

When naming molecular compound…

1st word: Non-metal that is first in the formula

2nd word: Non-metal that is second in the formula (ending changed to “ide”)

*Prefixes correspond to the subscript of each element (DO NOT write mono if the FIRST non-metal has only one atom)

Name the compound: N(2)O(5)

Dinitrogen Pentoxide

Name the Diatomic molecules.

H, N, F, O, I(s), Cl, Br(l)

What is a diatomic molecule?

Diatomic molecules cannot exist on their own without a 2 subscript

Name the following: O(2)

Oxygen Gas
