Given in the nuclear notation given, draw the Bohr model diagram to best represent it. Determine the total number of electrons and them start filling in the rights from the lowest energy rings (close to nucleus) to the higher energy rings. Remember the order of filling: the 1st energy level is filling with 2 electrons, the 2nd energy level is filled with 8 electrons, the 3rd is filled with 8 electrons.
