i don't know any of the others off the top of my head :(

Answer 2

its ok thanks tho

Answer 3

If the question says calcium ion, do you need the configuration for calcium (Ca) or Ca^2+? Because if its for the ion, then you would just need to take away two electrons from the configuration kah.x did :)

Answer 4

it just says calcium ion

Answer 5

@jebonna is right. i just gave you the configuration for calcium, which is different than a calcium ion

Answer 6

i think it wants the configuration not the ion

Answer 7
