Naming Ionic compounds

Front

What is an ionic compound?

Back

An ionic compound is a chemical compound composed of ions held together by electrostatic forces termed ionic bonding. They typically form between metals and nonmetals.

How do you name an ionic compound?

Back

To name an ionic compound, identify the cation (positive ion) and anion (negative ion), name the cation first followed by the anion, and modify the anion's name to end in '-ide' for simple ions.

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

Back

The charge of a cation can be determined from its position in the periodic table; for example, Group 1 elements form +1 cations, Group 2 elements form +2 cations.

What is the difference between ionic and covalent compounds?

Back

Ionic compounds are formed by the transfer of electrons from one atom to another, while covalent compounds are formed by the sharing of electrons between atoms.

What is the significance of Roman numerals in naming ionic compounds?

Back

Roman numerals indicate the oxidation state of the metal cation in compounds with variable charges, such as transition metals.
