Orbital-Filling Diagram for Bromine


Orbital-Filling Diagram for Bromine

Bromine has 35 electrons, so it will have 35 arrows placed in its orbital-filling diagram as in figure 13. The order bottom to top, adding the electrons  to the various sublevels, is 1s, 2s, 2p, 3s, 3p, 4s, 3d and 4p. Notice that the 3d sublevel is filled after the 4s and before the 4p. Remember, always fill the lowest energy  level first. This is consistent with the energy-shifted-electronic shell. Hund's Rule is demonstrated in the 4p sublevel.
