The electronic configuration of the elements determines the way in which the electrons are structured in the atoms of an element. It has 39 electrons and ends in a d orbital. Your formula predicts 9 valence electrons (2+8+18+9), which is false. This means part of the electron configuration has been replaced with the element symbol of the noble gas symbol. However, stability is gained by half-filling the 4d and the 5s subshells over the "expected" configuration. What is the electron configuration of niobium 2 plus? You can actually walk behind this almost 200-foot stunning waterfall. electronic configuration of chromium in shells.
