Calcium - Mass Nuer - Neutron Nuer - Ca

Calcium - Mass Nuer - Neutron Nuer - Ca. Mass nuers of typical isotopes of Calcium are 40; 42; 43; 44; 46. The total nuer of neutrons in the nucleus of an atom is called the neutron nuer of the atom and is given the syol N. Lithium is a chemical element with atomic nuer 3 which means there are 3 protons and 3 electrons in the atomic structure.
