A subscript that indicates the number of atoms typically appears to the lower right of the chemical symbol in a chemical formula. It represents the number of atoms of that element present in the compound.

The subscript in a formula typically indicates the number of atoms of an element present in a molecule. It is used to specify the ratio of atoms in a compound or the number of atoms in a polyatomic ion.
The number written after an element symbol that indicates the number of atoms of that element in a molecule is called a subscript. For example, in the chemical formula H₂O, the "2" is a subscript that indicates there are two hydrogen atoms for every one oxygen atom in the molecule. If no subscript is present, it is understood to be one atom of that element.
The subscripts in the formula for ethane (C2H6) represent the number of atoms of each element in the compound. In this case, "C2" indicates there are 2 carbon atoms, and "H6" indicates there are 6 hydrogen atoms in one molecule of ethane.
The subscript, the little number below and after the element, tells how many atoms are in a single molecule.
To determine the total number of atoms in the chemical formula Sq2R3, you need to consider the subscripts. The formula indicates there are 2 atoms of element Sq and 3 atoms of element R. Therefore, the total number of atoms is 2 (from Sq) + 3 (from R) = 5 atoms.
the purpose of a subscript is to tell how many atoms of that chemical is used in the formulaThe number of atoms of the same element in the molecule ~APEX
