First off the shells are named in the order (their principle quantum number, this is essentially a radius from the nucleus): first, second, third, etc also referred to as k, l, m...
now the subshells are given by s, p, d, f, g, h... where s is spherical, p follows along the planar axis intercept lines, d has some ring shapes, and the next few are too detailed to describe.
subshell s can hold 2 electrons
the 3p subshells each hold 2, totaling up to 6
the 5d subshells hold 2 e- each, totalling 10
then 7f for 14, (the 9g for 18, and the 11h is for 22) g and h are expected by trend to be this way as we only currently have filled the f shells and the first g to be filled would be with the elements in the 8th period (currently no known elements).
1s2, 2s2, 2p6, 3s2, 3p6, 4s2, 3d10, 4p6, 5s2, 4d10, 5p6, 6s2, 4f14, 5d10, 6p6, 7s2, 5f14, 6d10, 7p6 (this would be the structure of element 118) and then the next would fill 8s2, 5g18, 6f14, 7d10, 8p6 (this would be the element that someday falls under element 118 on our periodic table).
