Silicon has 2 electrons in the 3p sublevel in its ground state. Silicon's full electron configuration is: 1s2 2s2 2p6 3s2 3p2.
Oxygen, [He]2s22p4

An atom of antimony in its ground state has 3 unpaired electrons.
There are many elements which have no unpaired electrons in their outer shells. The Noble gasses all have closed shells of valence electrons. The alkali earth metals (Beryllium, Magnesium, Calcium etc) also have no unpaired electrons, although their outer shell is not entirely full.
1 unpaired electron
Not in its ground state.
The elements in group 15 Nitrogen, N; Phosphorus, P; Arsenic, As; Antimony, Sb and Bismuth, Bi all have a ground state with 3 unpaired electrons in p orbitals.

An atom of antimony in its ground state has 3 unpaired electrons.
There are 5 unpaired electrons in Fe^3+ in its ground state.
That would be 0. The ground state of every element except for Hydrogen is 1s2 which has no unpaired electrons. (only valence electrons have the ability to be unpaired). Full configuation of Fe would be: 1s2 2s2 2p6 3s2 3p6 4s2 3d6 WWWWWWWWWRRRRRRROOOOOOONNNNNNGGGGGGG!!!!!!!
Two. The ground state configuration of Sulfur is [Ne] 3s23p4. According to Hund's rule, the p orbitals must fill up separately first. This results in the first 3 electrons going into separate orbitals, and the fourth then doubles up with the first, leaving the other two p orbitals with unpaired electrons.

Magnesium has five unpaired electrons and is therefor paramagnetic
There are 0 unpaired electrons which would make it diamagnetic
