About the subscript zero symbol

Subscript Zero is a small, lowered digit zero used to denote the number zero in a subscript position. It appears as a miniature version of the standard digit zero, positioned below the baseline of surrounding text. This character is primarily employed in mathematical, scientific, and chemical notation, where it appears in formulas such as chemical formulas (e.g., H₂O) or mathematical expressions requiring a zero index or base. It belongs to the set of subscript numerals that allow for precise typographic representation of subscripts in plain text.
