The 4p orbital of a bromine (Br) atom is predicted to contain a total of 5 electrons.
Bromine has an atomic number of 35, which means it has 35 electrons when neutral. The electron configuration of bromine is:
- 1s2
- 2s2
- 2p6
- 3s2
- 3p6
- 4s2
- 3d10
- 4p5
From this configuration, you can observe that after filling the 4s and 3d orbitals, the 4p orbital begins to fill with 5 electrons. The maximum capacity of any p orbital is 6 electrons, but since bromine has 5 in the 4p orbital, we know it is just short of full. This is crucial in understanding its chemical behavior and how it bonds with other elements.
