Ionic and Covalent Nomenclature

Front

What is ionic nomenclature?

Back

Ionic nomenclature is the system used to name ionic compounds, which consist of cations (positively charged ions) and anions (negatively charged ions).

What is covalent nomenclature?

Back

Covalent nomenclature is the system used to name covalent compounds, which are formed by the sharing of electrons between nonmetal atoms.

How do you determine the charge of a cation in an ionic compound?

Back

The charge of a cation is determined by the group number of the element in the periodic table; for example, group 1 elements form +1 cations.

Front

How do you determine the charge of an anion in an ionic compound?

Back

The charge of an anion is typically determined by the group number of the element in the periodic table, with nonmetals usually forming anions with a charge equal to 8 minus their group number.

What is the significance of prefixes in covalent nomenclature?

Back

Prefixes in covalent nomenclature indicate the number of atoms of each element in the compound, such as 'di-' for two and 'tri-' for three.
