There are 6 unpaired electrons in Cr because it is an exception atom when doing electron configuration. Because of the extra stability with a full subshell, one of the two electrons in the 4s orbital will move up to the 3d orbital (which originally had only 4 unpaired) to make the 3d orbital full.
Now, there is one unpaired electron in the 4s orbital and 5 unpaired electrons in the 3d orbital, which adds up to 6 total.
None - it is an inert gas
Ge atoms have two unpaired electrons.

An atom of antimony in its ground state has 3 unpaired electrons.
Not in its ground state.

Magnesium has five unpaired electrons and is therefor paramagnetic

3 unpaired electrons
An atom of antimony in its ground state has 3 unpaired electrons.
There are 5 unpaired electrons in Fe^3+ in its ground state.
Not in its ground state.
1 unpaired electron
There are 5 unpaired electrons in Fe^3+ in its ground state.
Magnesium has five unpaired electrons and is therefor paramagnetic
Hund's Rule

0
Add the electrons in accordance with the aufbau principle and then count the unpaired ones.
There are 0 unpaired electrons which would make it diamagnetic
