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.
A proton is a positively charged particle located in the nucleus of an atom. An electron has $\frac{1}{1836}$ times the mass of a proton, but an equal and opposite negative charge. An elementary charge -- that of a proton or electron -- is approximately equal to 1.6Ã10-19Coulombs. Unlike protons, electrons can move from atom to atom. If an atom has an equal number of protons and electrons, its net charge is 0. If it gains an extra electron, it becomes negatively charged and is known as an anion.
