How many neutrons are in an atom of calcium
WebThe mass number of an atom is calculated by adding together the number of protons and neutrons that are found within that atom, as shown below. Mass Number = # of Protons … WebThe total number of neutrons in the nucleus of an atom is called the neutron number of the atom and is given the symbol N. Neutron number plus atomic number equals atomic mass number: N+Z=A. The difference between the neutron number and the atomic number is known as the neutron excess: D = N – Z = A – 2Z.
