http://faculty.sfasu.edu/janusama/CHE111/Assignment012.htm WebWe know that the atomic number of calcium is 20 and the atomic average mass number is about 40. Neutron = 40 – 20 = 20. Therefore, a calcium atom has twenty neutrons. Based on the atomic number, mass number, and neutron number of the element, three things can be considered. These are isotope, isobar, and isotone.
