A subscript is a short letter or number that is formatted to the right of the baseline to make a word, number, or formula that makes sense. Examples: H2O, NH3, O2 + H2O ⇌ HO2 + OH, NO + HO2 NO2 + HO, CO2, C2H2, H2C2O,CH3COOH, etc.
A superscript is a small letter or number that is placed to the right of the power to form a meaningful word, number, or formula. Examples: X2, (a2+b2) =a2+b2+2ab, HeH+, OH+, etc.
