Check against a reference answer
Almost all an atom’s mass is concentrated in its tiny nucleus, which contains protons and usually neutrons. Electrons have comparatively negligible mass. The positive charge is concentrated in the nucleus because protons are positive. The atom as a whole is neutral because it has equal numbers of protons and electrons.
