The 2 plus signs indicate that the calcium ion (Ca2+) has a charge of +2. This means that the calcium atom has lost 2 electrons, giving it a positive charge of 2. It is an ion that is positively charged and forms in certain chemical reactions.
If you mean Ca(OH)2(s) --> Ca2+(aq) + 2OH-(aq) this is the equation for the dissolving of calcium hydroxide in water.
The charge of Ca2+ is correct. Calcium typically oxidizes to form a 2+ cation by losing two electrons.
Ca2+ is a cation formed by Calcium to become stable and attain the noble gas configuration of Argon. Calcium forms this cation by losing two electrons
The particle Ca2+ is bigger in size compared to the Ca particle. This is because Ca2+ has an additional charge compared to Ca, which results in a larger ionic radius due to increased electron-electron repulsion that can overcome the attractive force between the nucleus and electrons.
The chemical formula for combining Ca2+ and AsO3^4- ions would be Ca3(AsO3)2. This shows that three calcium ions (Ca2+) will combine with two arsenite ions (AsO3^-4).
If you mean Ca(OH)2(s) --> Ca2+(aq) + 2OH-(aq) this is the equation for the dissolving of calcium hydroxide in water.
The ionic compound formed by Ca2+ and F- ions is calcium fluoride.
An isotope of calcium
The charge of Ca2+ is correct. Calcium typically oxidizes to form a 2+ cation by losing two electrons.
In this reaction, Ca2+ reacts with NO2^1- to form Ca(NO2)2. The balanced chemical equation for this reaction is: Ca2+ + 2NO2^- → Ca(NO2)2.

Carbon dioxide (gas), water and Ca2+ ions.
They have the same electron configuration as argon, which means they are isoelectronic with argon.
