Explanation:
Detailed explanation-1: -Notice in the formula CH4 that there is a number written lower and smaller after the symbol for hydrogen. This is called a subscript. Subscripts show the ratio of atoms of different elements in the compound. Since there are four hydrogen atoms in the molecule, the subscript 4 follows the symbol for hydrogen.
Detailed explanation-2: -Subscripts. We use subscripts in chemical formulae to indicate the number of atoms of an element present in am molecule or formula unit. There are no exceptions to this.
Detailed explanation-3: -To find out the number of atoms: MULTIPLY all the SUBSCRIPTS in the molecule by the COEFFICIENT. (This will give you the number of atoms of each element.)
