Lithium atoms contain one unpaired electron. Two of the three total electrons in a lithium atom are paired in its lowest energy s orbital, which can contain only two.

In a neutral atom of lithium-7, the number of protons equals the number of electrons. The atomic number of lithium is 3, which is the number of protons. So a neutral atom of lithium-7 has 3 protons and 3 electrons.
The number of electrons in each lithium atom is 3.
A silicon atom has 4 unpaired electrons.
It is the number of unpaired electrons in their valence shells. Oxygen has two unpaired valence electrons and carbon has four unpaired valence electrons.

It is the number of unpaired electrons in their valence shells. Oxygen has two unpaired valence electrons and carbon has four unpaired valence electrons.
They are the same you are retarted my god you fruit cake gypsy
An atom of antimony in its ground state has 3 unpaired electrons.
