How do I know if copper(II) is the positive or negative ion?

Question

anonymous · Answer

copper is a metal and it is always positive, some rare metals can have negative ions (anions) cause they can more easily release electrons than recieve them.

Thanks.
So all Metals with numbers are taken as positive ions?
What about non-metals and metalloids?

anonymous · Answer

all metals are positive yes, and metalloids can more easily have negative ions cause their electronegativity is greater than those of metals

anonymous · Answer

so if I would have a metalloid with a number, how would i know if it's an anion or cation?

anonymous · Answer

well you assume it is a cation cause cations are those who are written with roman numbers like copper (II) sulphate ... cause cations are those who dyrect anions and ligands...
