The difference between the mass number and the atomic number () gives the number of neutrons in a given nucleus. For example: Carbon-14 is created from Nitrogen-14 with seven protons and seven neutrons via a Cosmic Ray interaction which changes 1 proton into 1 neutron. Thus the atomic number decreases by 1 (Z:7->6) and the mass number remains the same (A = 14), however the number of neutrons increases by 1. :Before: Nitrogen-14 (7p, 7n) :After: Carbon-14 (6p, 8n). |
