The alkaline earth metal calcium has 20 protons in its nucleus. That's what makes it calcium; it's what gives it its elemental identity. It's in Group 2 of the Periodic Table. The number of neutrons in calcium varies, however, and there are several different isotopes of this metal. The four stable isotopes of calcium (Ca) are Ca-40, Ca-42, Ca-43 and Ca-44, which have 20, 22, 23 and 24 neutrons in their nuclei, respectively. About 97% of naturally occurring calcium is Ca-40.
There are a number of other isotopes of calcium, and they range from Ca-34 to Ca-57. It should be noted that Ca-46 and Ca-48 have extremely long half-lives, and are pretty stable. The interesting isotope is Ca-41, which is produced by neutron capture from Ca-40. This makes it of interest in the study of stars. Use the links below for more information.
In general, calcium is said to have an estimated 20 neutrons.
