An oxygen atom has 8 electrons, and thus 6 valence electrons. 4 of these are paired, giving us 2 unpaired lectrons. This also means oxygen can connect to 2 other atoms through a basic bond, or 1 atom through a double bond.
O2 has two unpaired electrons. The O atom has two unpaired electrons.
according to molecular orbital theory, oxygen molecule being diatomic has two unpaired electrons in the pi* anti bonding molecular orbital. hence, it is para magnetic.
There are two unpaired electrons in an oxygen atom.
An oxygen atom has two unpaired electrons in its ground state.

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
Molecular orbital theory predicts that ground state diatomic oxygen has two unpaired electrons (it is a diradical) which occupy its pi orbitals. These unpaired electrons produce a magnetic moment and are responsible for the paramagnetic property of diatomic oxygen.

Add the electrons in accordance with the aufbau principle and then count the unpaired ones.
