A
physcial property
B
chemical property
C
chemical formula
D
atom
Explanation: 

Detailed explanation-1: -A molecular formula is a representation of a molecule that uses chemical symbols to indicate the types of atoms followed by subscripts to show the number of atoms of each type in the molecule. (A subscript is used only when more than one atom of a given type is present.)

Detailed explanation-2: -The subscript indicates the number of molecules/atoms in a formula.

Detailed explanation-3: -In a chemical formula, the letters represent the atomic symbol of each atom. The subscript (lower) represents the number of each atom, while the superscript (higher) represents the charge on a given atom. A coefficient before a chemical formula represents that many units of the molecule.

Detailed explanation-4: -The molecular formula is an expression that defines the number of atoms of each element in one molecule of a compound. It shows the actual number of each atom in a molecule. For example, the molecular formula of propane is C4H10.
