WebIn all the chemistry of the transition elements, the 4s orbital behaves as the outermost, highest energy orbital. The reversed order of the 3d and 4s orbitals only seems to apply to building the atom up in the first place. In all other respects, the 4s electrons are always the electrons you need to think about first.

Web17 de out. de 2016 · 1 Answer Truong-Son N. Oct 17, 2016 It is the highest-energy atomic orbital in an atom that is filled with electrons. It is otherwise known as a valence orbital, or a frontier orbital (i.e. an orbital at the "frontier" of chemical reactions, performing the interesting legwork to move the reaction forward). WebEach shell has a different energy level, increasing the further it is from the nucleus. Each energy level is given a number called the principal quantum number, n. The closest shell has a value of n=1. The next shell has a …
