  1. For n = 1 you may have 2 s electrons.
    For n = 2 you have have 2s and 6p electrons.
    For n = 3 you may have 2s and 6p and 10 d electrons. Those 10 d electrons have ml = -2...-1...0...+1...+2 and put in electrons of 2 each under -2, 2 more under -1, 2 more under 0 and 1 more under +1. Add all of the electrons and I come up with 25. Check my thinking. Look up element 25 on the periodic chart.
    The second one is done the same way but you know that n = 1, n = 2 and n = 3 are filled so that's 18 to start and you only need to worry about whats in n = 4.
