Calcium’s atomic number is 20. it forms ions with 18 electrons. what is the electrical charge of a calcium ion?
Gnom [1K]
It would be a positive charge because it lost two electrons, if the charge was neutral it would be the same amount of protons and electrons, if the charge was negative the electrons would be 20 instead of 18. So in this case it is positive.
