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. WebCalling names. All atoms of a given element have the same number of protons in the nucleus. This number is the atomic number of the element and we give it the symbol Z . For example, lithium atoms contain 3 protons. The atomic number of lithium is 3. Any atom that has 3 protons must be a lithium atom. keith foulke red sox
