This would be an atom.
The representative particle of a sodium ion is Na⁺, which has lost one electron to become positively charged.
The smallest representative unit of a substance is called a molecule. The number and type of atoms present in a molecule are determined by the chemical formula of the substance. The chemical formula provides information on the number and type of each element present in the molecule.
the chemical formula for carbon is C and for chlorine is Cl.
The formula for hydrogen hydroxide is H2O.
Not formula, but chemical symbol is Pu. No, he means formula (eg: Table Salt/ Halite - NaCl)
The representative particle of a sodium ion is Na⁺, which has lost one electron to become positively charged.
If you think to formula unit this is Na2S.
No, they do not. When charged atoms, or ions, unite in an ionic bond, they form what is called a "formula unit," which is the smallest representative particle of an ionic compound. A molecule is the smallest representative particle of a covalent compound, which involves another type of bonding where electrons are shared rather than transferred.
A chemical formula is representative for the molecule composition.
The more adequate term is "formula unit".

Molecule
Ionic compounds do not contain molecules. The representative particle of an ionic compound is called a formula unit. Molecules are the representative particles of a covalent compound.
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 representative particles for covalent compounds are molecules, which consist of two or more nonmetal atoms chemically bonded together by sharing electrons. These molecules are the smallest units of a covalent compound that retain the compound's chemical properties.
The chemical formula is representative for a molecule and give indication about the chemical composition.
H - Hydrogen Smallest particle with formula H2O is water molecule and is composed of two atoms of hydrogen and one that of oxygen. two atoms of hydrogen incidentally combined to make one hydrogen molecule. Thanks, Dilip Thakur
