I am not doing them all for you I will talk you though an example: Ca 1s2, 2s2, 2p6, 3s2, 3p6, 4s2, Shells of electrons are made from sushells (s,p,d,f) s subshell holds 2 electrons, p holds 6 electrons and d holds 10 the first shell only contains an s orbital so the maximum number of electrons in the first shell is 2 The second has s+p 2+6 8 The 3rd has s+p+d 18 The tricky thing here is that the 4s orbital fill before the 3d subshell
