About the subscript four symbol

The subscript four is a small numeral positioned below the baseline, used to represent the digit 4 in a lowered form. It appears in chemical formulas, mathematical expressions, and scientific notation to indicate the number of atoms in a molecule, a sub-index in a sequence, or a lower index in a variable name. The character belongs to the Superscripts and Subscripts block and is classified as an other number symbol, meaning it functions as a numeric digit rather than a letter or punctuation mark.
