When building an atom, pay close attention to the particles' electrical charges. Protons have a charge of +1. Electrons have a charge of -1. Neutrons are neutral, as its name implies. A stable ...

So the atom has no overall charge - it is neutral ... This Van de Graaff generator helps to build up electrical charge so we can see its effects. Electrons are picked up by the rubber belt ...

Some friendly advice: Try to keep the atom's overall electrical charge balanced. You'll never complete your atom if you don't. Why is diamond so hard? One reason is that the chemical bond between ...
