Chemistry

The traditional calcium atom has twenty protons and twenty electrons making it neutral.


The calcium in the pic is a calcium ion so the number of protons and electrons are not equivalent.


Since it's 2+ that means the ion is positively charged and for that to happen electrons are away.

So 20-2=18

There are 18 electrons
