calcium is an element with atomic nuer20. Stating …
i) The atomic nuer of calcium is 20. Its electronic configuration is 2,8,8,2. The valency of calcium is +2. Hence it is a metal belong to the group 2. ii) The radius of calcium is smaller than potassium because both elements lie in the third period of the periodic table. Potassium lies to the left of calcium in the period, and atomic size decreases, going left to right due to increase in the
Chemistry for Kids: Elements - Alkaline Earth Metals
Calcium and magnesium are important for animal and plant life. Calcium plays an important role in helping us to build strong bones and magnesium is used to help regulate the body''s temperature.

Calcium ions in crystal structures generally bind to oxygen atoms in ligands (rather than any other element), and their preferred coordination nuers range from 6 to 8. In protein crystal structures the tendency of calcium to bind water molecules is less than for magnesium (1.5 versus 2.2 water molecules on the average per metal ion site, respectively).
