Neutrons are neutral, as its name implies. A stable atom has a net charge of 0. In other words, it has an equal number of protons and electrons. The positive protons cancel out the negative electrons.

Because the mass of a proton is equivalent to a neutron, the relative mass of an atom is the same as its nucleon (mass) number. Neutrons have no charge. Protons are positively charged. So the ...

The picture shows a close-up of one carbon atom. A hydrogen atom has one proton as the nucleus ... electrons from the skin are transferred to the plastic giving the plastic a negative charge. When the ...
