How many electrons does a ca2+ ion have
WebWikipedia WebAug 3, 2024 · Ca 2+ represents that a calcium ion has 20 protons and 18 electrons. The 2+ charge in the superscript indicates that there is a loss of two electrons, i.e. 2-2 = 18. As indicated, when atoms form ions, they either lose or gain electrons. When there is no change in the number of protons and neutrons, it is known as a nucleus, which remains intact.
