Copper has 29 electrons in total, so the rearmost electrons are lined up as …4s^2-3d^9. Both of the configurations have the correct numbers of electrons in each orbital, it is just a matter of how the electronic configuration notation is written (here is an explanation why). An electron would happily make a leap to an adjacent shell of relatively equivalent energy to attain a more stable configuration. The 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. Electron configuration of Copper is [Ar] 3d10 4s1. These are placed in the middle of the periodic table, between s and p-block elements due to their chemical behavior like boing point, melting by specific heat, density, ionization energy, bonding, etc.The general electronic configuration of valence electron … It is an intensive property, which is mathematically defined as mass divided by volume: Electron affinity of Copper is 118.4 kJ/mol.
