Quick Answer. The net electric charge of the nucleus of an atom is positive due to the presence of charge-carrying particles known as protons. The outer shell of the atom is negatively charged as a result of carrying electrons in a diffuse cloud. Atoms always have a net neutral electric charge.
The nucleus, that dense central core of the atom, contains both protons and neutrons. Electrons are outside the nucleus in energy levels. Protons have a positive charge, neutrons have no charge, and electrons have a negative charge. A neutral atom contains equal numbers of protons and electrons. But the number of neutrons within an atom of a particular element can vary. Atoms of the same element that have differing numbers of neutrons are called isotopes.
