The general formula for an acid is H n X, where X is an anion, H is a hydrogen ion, and n is the number of hydrogen ions needed to make the acid neutral. Binary acids are named by using the prefix hydro-, the root name of the anion, and the suffix -ic, plus the word acid.
Compounds are formed when two or more elements chemically combine, resulting in the formation of bonds. For example, hydrogen and oxygen can react to form water, and sodium and chlorine can react to form table salt.
1. The name contains two words. 2. Covalent compounds that contain hydrogen begin with hydrogen. Compounds that contain oxygen end in prefix-oxide. (This rule takes precedence over other rules below). 3. The first root word in the name is the name of the element that is in a column farther to the left in the periodic table. 4.
