A subscript is a small number or symbol placed below and to the right of a mathematical expression, chemical formula, or other scientific notation. Subscripts are used to indicate various aspects of a scientific concept, such as the atomic number of an element, the charge of an ion, or the position of a particular atom or group of atoms within a molecule. In chemistry, subscripts are used to denote the number of atoms of each element in a compound. For example, the subscript in the chemical formula H2O indicates that there are two hydrogen atoms and one oxygen atom in a molecule of water. In physics, subscripts are used to indicate the components of a vector or tensor. For instance, the subscript i in the expression v_i represents the i-th component of a velocity vector.
