It is important to keep a constant concentration of calciuum in the blood under many different condiotions sch as different forms of food, starve f.x. And preserve the body from loss of calcium from the kidneys and the skeleton and ensure growth in children and young people
Ca2 is basically two Ca's so it's larger (the plus doesn't compensate)
they cannot bond together, they are separate .
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
If you mean Ca(OH)2(s) --> Ca2+(aq) + 2OH-(aq) this is the equation for the dissolving of calcium hydroxide in water.
Ca3(AsO4)2
Ca2 is basically two Ca's so it's larger (the plus doesn't compensate)
Ca2+ and Br- obviously must form, CaBr2 Calcium bromide
An isotope of calcium
Calcium Ion
they cannot bond together, they are separate .

Ca(NO2)2
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 protein that changes shape when calcium ion (Ca2+) binds to it, is the troponin. It is a regulatory protein that is a component of the thin filament.
If you mean Ca(OH)2(s) --> Ca2+(aq) + 2OH-(aq) this is the equation for the dissolving of calcium hydroxide in water.
Carbon dioxide (gas), water and Ca2+ ions.
Its a positive calcium ion that loses two electrons.
