For each set of elements represented in this periodic table outline, identify the principal quantum number, n, and the azimuthal quantum number, ℓ, for the highest energy electrons in an atom of one of those elements.

Here are the elements

Potassium(K)
Radon(Rn)
Bohrium(Bh)
Neon(Ne)
Lanthanum(La)

Please help. Im just so lost. Ive been at this for hours and I am so confused! Thanks!

1) electronic configuration of potassium (K) = 1s2 2s2 2p6 3s1 3p6 4s1
n = 4 ; l = 0
2) electronic configuration of bohrium (Bh) = 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f14 5d10 6p6 7s2 5f14 6d5
n = 6 ; l = 2
3) electronic configuration of radon (Ra) = 1s22s22p63s23p63d104s24p64d105s25p64f145d106s26p6
n = 6; l = 1
4) electronic configuration of neon (Ne) = 1s2 2s2 2p6
n = 2; l = 1
5) electronic configuration of lanthanum (La) = 1s22s22p63s23p63d104s24p64d105s25p65d16s2
n = 6 ; l = 0
