Zinc is an element in the d-block of elements. Remember that the first eight were placed during our trip through the third period/row. d.) zinc has 2 valence electrons - both are in the 4s sublevel. C. greater, because chlorine has a greater nuclear charge which translates into a greater force exerted on electrons. Thus, although a nickel atom has, in principle, ten valence electrons (4s 2 3d 8), its oxidation state never exceeds four. Valence electrons are those electrons that reside in the outermost shell surrounding an atomic nucleus. Valence electrons are of crucial importance because they lend deep insight into an element’s chemical properties: whether it is electronegative or electropositive in nature, or they indicate the bond order of a chemical compound – the number of bonds that can be formed between two atoms. To see how many of these electrons are valence electrons, write the electron configuration of a neutral zinc atom.
