Molecular Compounds

Held together by covalent bonds

Elements involved are nonmetals

Binary Compound: two nonmetals

Example: H2O

Molecular Compounds

Nonmetals can combine in different ways

Use prefixes to distinguish between the combinations

Example: CO and CO2

Prefixes indicate how many atoms of an element are present in each molecule of the compound CO2 = Carbon dioxide

Naming Binary Compounds

1. Write the names in the order of the formula

2. Use prefixed to indicate the number of each kind of atom If the first element has just one atom, do not use

a prefix

3. End the name of the second element with “ide”
