Silicon has 2 electrons in the 3p sublevel in its ground state. Silicon's full electron configuration is: 1s2 2s2 2p6 3s2 3p2.
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.
3 electrons. This can be told from the periodic table. These electrons are in the 2p orbital.
Iodine has one unpaired electron in its ground state.
Magnesium has five unpaired electrons and is therefor paramagnetic
Phosphorus has three unpaired electrons in its ground state.
An atom of antimony in its ground state has 3 unpaired electrons.
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.

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!!!!!!!

Iodine has one unpaired electron in its ground state.
There are 5 unpaired electrons in Fe^3+ in its ground state.
Magnesium has five unpaired electrons and is therefor paramagnetic
There are 0 unpaired electrons which would make it diamagnetic
The element with three unpaired electrons in its p orbital is phosphorus. Its electron configuration is [Ne] 3s^2 3p^3, where the last three electrons occupy three separate p orbitals, each with one unpaired electron.
