Understand that metal ions are atoms of metals that have lost one or more electrons.
Recall that electrons carry a negative charge, so losing electrons results in a net positive charge on the ion.
Recognize that because metals lose electrons, their ions always have a positive charge.
Note that this is different from nonmetals, which often gain electrons to form negatively charged ions.
Therefore, metal ions always have a positive charge due to the loss of negatively charged electrons.
