How Many Valence Electrons Does Roentgenium Have
Vanadium has 2 valence electrons because if you look at the electron configuration the first shell has 2 the second 8 the third 11 and the last shell where the valence electrons are has 2. Each electron is influenced by the electric fields produced by the positive nuclear charge and the other Z 1 negative electrons in the atom.
