Yellow, nonmetallic element belonging to group 16 of the periodic table. It is an essential element in living organisms, needed in the amino acids cysteine and methionine, and hence in many proteins. Absorbed by plants from the soil as sulphate ion. Description from mendeleev.

The outermost shell: the valence electronsThe inner shellsThe nucleus One bead for each electron, on the ring of its shell, counted from the nucleus out. The rings turn at their own pace; the model is Bohr's picture of the atom, which places electrons in shells but not on true orbits.

Screening of each subshell

Clementi's screening constants: how much of the nucleus's charge the other electrons hide from an electron in each subshell. What is left is the effective nuclear charge it feels.
