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.
How to Write the Electron Configuration for Lithium. Lithium is the third element with a total of 3 electrons. In writing the electron configuration for lithium the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the remaining electron for Li goes in the 2s orbital. Therefore the Li electron configuration will be 1s22s1.
