stability of calcium carbonate with metals in israel
Alkaline earth metal — Wikipedia Republished // WIKI 2
The alkaline earth metals are six chemical elements in group 2 of the periodic table. They are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). The elements have very similar properties: they are all shiny, silvery-white, somewhat reactive metals at standard temperature and pressure.

Low calcium intake may also be a risk factor in the development of osteoporosis. The best-absorbed form of calcium from a pill is a calcium salt like carbonate or phosphate. Calcium gluconate and calcium lactate are absorbed well by pregnant women.
Carbonate chemistry — Science Learning Hub
Calcium carbonate is unusual in that its solubility increases as the temperature of the water decreases. The increased solubility of calcium carbonate in rainwater saturated with carbon dioxide is the driving force behind the erosion of limestone rocks, leading to the formation over long periods of time of caverns, caves, stalagmites and stalactites.

Calcium - Simple English Wikipedia, the free encyclopedia
Calcium is a chemical element. Its syol on the periodic table (a list of all the elements) is Ca. Its atomic nuer is 20. (The atomic nuer says where Calcium sits in the periodic table.) It has 20 protons and 20 electrons (if is an atom, see ion). The most common isotopes are Ca-40 and Ca-44. Its mass nuer is about 40.08. Calcium is
