Explanation / Answer

Ok, so in the first question... which one of the three elements arein the same column in the periodic table of elements. So theanswer is e) The other I believe is e) as well. Orbitals are 1s, 2s, 2p,3s, 3p, followed by 4s and so on... so all the options given havemore orbitals than just three.
