The atomic number of an element is equal to the number of protons and electrons in that element. This fact has key implications for the building up of the periodic table of elements. The number of electrons in each elements electron shells, particularly the outermost valence shell, is the primary factor in determining its chemical bonding behavior. And so since mass numbers 31 member of protons and electrons should be 31 Find the number of neutrons we need to subtract. Made an educated seminar fun. Tim Maggio, Auto-Wares", , A:Given Atomic number of the element =. It shows the electron as a particle orbiting the nucleus, similar to the way that planets orbit the sun.
