Positive ions are elements which have lost one or more electrons to become positively charged.

Hydrogen forms positive ions in some compounds and it is these H⁺ ions which can make solutions acidic.

Positive ions are attracted to negative ions and to the negative electrode (cathode) during electrolysis.


Lithium forms +1 ions.	Magnesium forms +2 ions.	Aluminium forms +3 ions.
