Answer:
A sulfur ion with a charge of -2 = S⁻²
An iron ion with a charge of +3 = Fe⁺³
A chlorine ion with a charge of -3 = Cl⁻³
Explanation:
Anion:
Anion are formed when an atom gain the electrons.
Representation:
The anion of an atom is showed by adding the number of electrons gained by atom with negative sign as superscript on the symbol of an atom.
Cation:
Cation is formed when an atom lose the electron.
Representation:
The cation of an atom is showed by adding the number of electrons lose by an atom with positive sign as superscript on the symbol of an atom.
