An ion (or a charged atom).
ion
For covalently bonded particles, the smallest identifiable unit of a compound is a molecule. For ionic compounds, the smallest identifiable unit of a compound is a formula unit.
If it's a molecular compound, the smallest amount would be one molecule. If it's an ionic compound, the smallest amount is a formula unit.
An ionic compound is an example of a chemical compound.
A covalent compound, not ionic

If it is a molecular compound, the smallest unit is called a molecule. If it is an ionic compound, the smallest unit is called a formula unit.

If it is an element, then the smallest particle that retains the characteristics of the element is an atom. If it is a diatomic element, then the smallest particle that retains the characteristics of the element is a molecule. If it is a molecular compound, then the smallest particle that retains the characteristics of the compound is a molecule. If it is an ionic compound, the smallest particle that retains characteristics of the compound is a formula unit.
The traditional answer is molecule. However, it is not now usual to refer to a formula unit of an ionic compound in this way.
particles called atoms are the smallest unit. Several atoms combine to make a molecule and molecules are what form substances such as water
