# oh poo
I'll take your word for that. why does it have to have two positive charges? why can't it just have one?

# because it's in group two, and so has two outer shell electrons,
and when metals become ions, they lose all their outer shell electrons, in this case two.

# it loses them?
then it wouldn't be an ion at all would it?
sorry it's been years since my lowly co-ordinated science GCSE :)

# no,
it becomes an ion by losing electrons. an ion is an atom that has either gained or lost electrons. metallic atoms lose electrons, and non-metals gain them.

# not just one with a charge?
And it's not a metal is it?
*confused & befuddled*
I've always called it ca+, and all the teachers / lecturers text books do, don't they? or has my mind just blocked out the 2 for the last 12 years or so for some bizarre reason?
