What is the charge for all elements in Group 1A?

##1+##

For starters, it's worth noting that located in group 1 of are called alkali metals.

All these elements have one valence electron, i.e. one electron located in their outermost energy shell. In order complete their octet and become stable, these elements lose that valence electron.

Consequently, group 1 elements will form ##1+## cations.
