What is a superscript in a chemical equation?
Ions, or charged atoms, have superscripts, or tiny numbers above the element’s symbol, and they show if an atom has gained or lost electrons. A positive superscript means the atom lost electrons whereas a negative superscript means it gained electrons.
What do subscripts and superscripts mean in chemistry?

If a charge is present, it’s indicated in superscript, with a sign (+/-) and a number if more than one charge is present. For example, calcium ions have two positive charges so are written Ca2+.
What is symbolic notation in chemistry?
A chemical symbol is a notation of one or two letters representing a chemical element. The exceptions to the one- to two-letter symbol are the temporary element symbols assigned to designate new or to-be-synthesized elements. Temporary element symbols are three letters that are based on the element’s atomic number.
