Why atom is usually electrically neutral?

An atom is usually electrically neutral because_____ equal number of electron proton square equal number of neutron electron square equal number of neutron proton square none of these square

The classical concept of atomic structure is that negative charges are uniformly distributed inside a sphere of radius R keeping the nucleus of positive charge Ze at the centre of that sphere. An atom as a whole is electrically neutral. find out the electric field at a distance r from the nucleus, according do this atomic model.
