Read each question carefully and follow the instructions to name the covalent compounds or write their chemical formulas. Remember the prefixes used for covalent nomenclature.
A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.
1. In naming covalent compounds, prefixes are used to indicate the number of of each element.
2. The prefix for one atom is , but it is usually omitted for the first element.
3. The ending of the second element in a covalent compound name is typically changed to .
