When electrons are removed in succession from an element, the transition from removing valence electrons to removing core electrons results in a large jump in ionization energy. By looking for this large jump in energy, we can determine how many valence electrons an element has, which in turn can help us identify the element. sew eurodrive encoder wiring diagramWebvalence electron configuration which of the following options correctly describe the group 8A elements? -they're called the halogen group -they exist as diatomic species -they have very low electron affinities -they have low ionization energies -all group 8A elements with n ≥ 2 have filled outer ns and np subshells sew eurodrive electric motor
