Question

magnesium is a monoatomic or not ​

Monatomic ions are chemically represented by the element's symbol with the size and type of charge written as a superscript to the right of the symbol. If the size of the charge is one, then the type of charge (+ or -) is all that is written. For example, the magnesium 2+ ion is written as Mg2+.
