An easy definition of valence electrons would be a single outer shell electron in the outer shell of an atom that is responsible for the chemical properties of the atom. In other words, a valence electron is an electron of an atom, located in the outermost shell of the atom, that can be transferred to or shared with another atom.

1. How many electrons does iron have?
Iron contains eight electrons in its valence shell. Because iron is a transition metal, electrons in its d subshells can be used as valence electrons. Valence electrons are electrons that exist outside of a noble-gas core in a transition metal. Iron has the electrical configuration 1s22s22p63s23p64s23d6.
