Homework Help: Alkali Metals and Ionization Energy

  1. Nov 4, 2005 #1
    Which alkali metal forms preferentially an oxide rather than a peroxide or superoxide?
    a. Na
    b. Rb
    c. Li
    d. K

    Of the following, which element has the highest first ionization energy?
    a. Na
    b. Al
    c. P
    d. Cl

    Are these correct? Thanks.

    d is right for the second one because Cl wants to gain an electron not loose one

    My guess would be c also for the first one just because Na, K, Rb all have similar chemistry and Li always is just weird for a alkali metal. But I cannot be entirely sure.
