Covalent Compounds Formed between two nonmetals. 1. First element in the formula (more metallic) is named first, using the full element name. 2. Second element named as if it were an anion (ends in ide) 3. Prefixes are used to denote the numbers of atoms present. 4. The prefix mono - is never used for naming the first element. 36

Acids Acids often recognized by hydrogen that appears first in formula HCl Molecule with one or more H + ions attached to an anion If the anion does not contain oxygen, the acid is named with the prefix hydro and the suffix ic. 39
