Calcium - Elements Database
Calcium (atomic nuer 20, syol Ca) is an alkaline earth metal and one of the most abundant elements found in the Earth''s crust in terms of mass. This soft gray element is rather hard, and it is important for life on earth, especially for cell physiology whereby the calcium ion Ca2+ moves out and into the cytoplasm, signaling different cellular processes.
