A molecule, as in a molecule of water.
A molecule is the smallest particle of a "compound" being that compounds are made up of more than one atom. The smallest particle of any "chemical element" that retains its properties would be the atom.
The covalent compound S4C6 is called tetrasulfur hexacarbide.
The covalent compound of NF3 is called nitrogen trifluoride.
The covalent compound CO is called carbon monoxide.
The covalent compound HCl is called hydrochloric acid.

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.
The covalent compound S4C6 is called tetrasulfur hexacarbide.
The covalent compound of NF3 is called nitrogen trifluoride.
The covalent compound CO is called carbon monoxide.
The covalent compound HCl is called hydrochloric acid.
The covalent compound N2O2 is called dinitrogen dioxide.
The covalent compound O2 is called oxygen gas.
The binary covalent compound P4O5 is called tetraphosphorus pentoxide.
The covalent compound CaSO4 is called calcium sulfate.
The covalent compound NCl3 is called nitrogen trichloride.
No, a covalent bond is formed between two atoms when they share electrons to achieve stability. A formula unit generally refers to the smallest ratio of ions in an ionic compound, not in covalent compounds.
