WebAtoms in the same row have varying numbers of valence electrons, but the number is always 8 or less. The inert gases (blue boxes) always hold 8 valence electrons (He is the exception). [1] Lewis postulated that inert gas atoms are chemically inert because they hold 8 valence electrons. WebSince iron is a transition metal, it can use electrons in its d subshells as valence electrons. A transition metal’s valence electrons are electrons that reside outside of a noble-gas core. The electronic configuration of iron is 1s 2 2s 2 2p63s 2 3p 6 4s 2 3d 6 . In the iron case, the electrons outside the noble gas core are 4s 2 3d 6 electrons.
