If an atom has the same number of electrons surrounding its nucleus as it has protons, the atom is considered to be electrically neutral. A simple example of this neutrality is with the Hydrogen atom which only has one proton (+) and one electron (-). The opposing charges from these particles create an electrically neutral atom.
