A variation on the theme of being âclosetedâ, which refers to the tendency to ignore, remove, falsify or re-explain evidence of bisexuality in history, academia, the news media and other primary sources.
The electronic configuration of Bromine is [Ar] 4s2 3d10 4p5 so there are seven valence electrons, two in the 4s orbital and 5 in the 4p orbital.
Start by writing the complete electron configuration of boron, #B#. Boron is located in period 2, group 13, and has an atomic number equal to #5#. This means that the electron configuration of a neutral boron atom must account for a total of #5# electrons. The complete electron configuration for a boron atom will look like this #B:  1s^2 2s^2 2p^1#
