Why solution of an electrolyte is electrically neutral ?

According to early model of an atom,the atom is considered it to have a positively charged point nucleus of charge Ze surrounded by a uniform density of negative charge up to a radius R . The atom as a whole is neutral. The electric field at a distance r from the nucleus is (r lt R)
