Detailed explanation-1: -A chemical formula tells us the number of atoms of each element in a compound. It contains the symbols of atoms of the elements present in the compound as well as how many there are for each element, in the form of subscripts.

Detailed explanation-2: -The chemical formula which represents the actual number of atoms of each element present in a molecule is known as molecular formula.

Detailed explanation-3: -The number of atoms of each kind is indicated by a subscript following the atom. If there is only one atom, no number is written. If there is more than one atom of a specific kind, the number is written as a subscript following the atom.

Detailed explanation-4: -Subscript Numbers When more than one atom of a particular element is present, subscripts are used to denote the exact number of atoms present. By convention, subscripts are always written to the bottom right of the element it is referring to. For example, a molecule of oxygen has two atoms, so it is written as O2 .

Detailed explanation-5: -Subscripts are numbers that come after a symbol and below. Subscripts tell you the number of. atoms of that element. If an element does not have a subscript, then it is understood that the subscript is 1. Li2Cl3 has two lithium atoms and three chlorine atoms.
