elements below, indicate how each elements’ valence electrons act in a chemical

reaction. Insert an L if an element loses electrons, a G if the element gains electrons, an E if the
element can either lose or gain electrons, and a U if the element is generally unreactive.

  1. Put an L on metals, G on nonmetals, and on He, and Ne, it is neither usually.

  2. I agree with metals and non-metals. For He and Ne and Ar I would go with a U since they are generally un-reactive.
    H can do either. (Loses to form H^+ and gains to form H^-)
