The number of atoms of the same element in the molecule
Not every chemical formula requires subscript. For example table salt is NaCl, sodium chloride. No subscript. But most chemical formulae do require subscript, such as water, H2O.
It is called a subscript. For example: In the formula for water (H2O), 2 is the subscript indicating that there are 2 hydrogen atoms in the compound .
The number of atoms of the same element in the molecule
Subscript
The number of atoms of that element in the molecule
The number placed below an element's symbol in a chemical formula is called a subscript. Subscripts indicate the number of atoms of that element in a molecule.
A subscript following a set of parenthesis in a chemical formula indicates that the entire group enclosed in the parenthesis is to be multiplied by the subscript outside the parenthesis. This is used to show the number of times a group of atoms or molecules is repeated in the compound.
Subscripts in chemical formulas indicate the relative proportions of the elements in a compound. They denote the number of atoms of each element present in a molecule. For example, in H₂O, the subscript "2" indicates there are two hydrogen atoms for every one oxygen atom in water. This helps to convey the composition and structure of the substance.

Changing a subscript in a chemical formula or equation alters the identity of the element or compound being referred to. For example, changing the subscript in H2O to H2O2 changes the compound from water to hydrogen peroxide, signifying a different chemical composition and properties. It is important to follow the correct subscript ratios to accurately represent chemical formulas.
To type small numbers for chemical formulas and exponents, you can use the subscript and superscript functions in most text editors or word processing software. In HTML, you can use for subscript and for superscript. You can also use keyboard shortcuts like Ctrl+= (for superscript) and Ctrl+Shift+= (for subscript) on some platforms.
The answer is 'subscript'
