Which is the correct way to write an ion symbol?
Conventions for Writing Ions. When writing the symbol for an ion, the one or two letter element symbol is written first, followed by a superscript. The superscript has the number of charges on the ion followed by a + (for positive ions or cations) or - (for negative ions or anions).
How are chemical symbols used to write formulas?
Chemical symbols are used to represent an atom or elements. E.g. The chemical symbol for hydrogen is H. The valency of an element is needed to be able to write the formulae of a compound. Recall that valency of an element is the number of valence electron the element has.
