An example of an atom that has no charge is one that has

a. 1 proton, 2 electrons, and 3 neutrons.
b. 3 protons, 1 electron, and 3 neutrons.
c. 2 protons, 2 electrons, and 1 neutron.
d. 3 protons, 2 electrons, and 1 neutron.

An example of an atom that has no charge is one that has :

C. 2 protons, 2 electrons, and 1 neutron.

The number of electrons and protons are the same.

It won't lose or gain electrons if it's a covalent bond it shares the electrons with another atom or atoms. if it is an ionic bond it will lose the 3 electrons on the outer shell and become a positively charged ion.  credit goes to @sunshinebaby of answers.yahoo.com.
