WebWhen the boron atom is excited, then the boron atom absorbs energy. As a result, an electron in the 2s orbital jumps to the 2p y orbital. So, the electron configuration of boron (B*) in excited state will be 1s 2 2s 1 2p x1 2p y1. The valency of an element is determined by electron configuration in the excited state. Web6 dec. 2024 · How many electrons does boron have in its outermost shell? three electrons Every element in the boron group has three electrons in its outermost shell (so-called valence electrons), and for each element there is a sharp jump in the amount of energy required to remove the fourth electron, reflecting the fact that this electron must be …
