Atoms are composed of three particles with an electric charge: electrons, protons and uncharged neutrons. Electrons have a negative charge, and protons have a positive charge. The negative charge of ...

Yale scientists have come one step closer to understanding the behavior of electrons and have found surprising results. Coulomb’s law — a law governing electrical force between charged objects — as it ...

The 'fluid' model of electricity, developed in the eighteenth century by Benjamin Franklin and others, postulates that electrical charge is a continuous quantity associated with an excess or deficit ...

The electrons in a three-dimensional metal can be described as a ‘Fermi liquid’, in which electrostatic – or Coulomb – interactions between the negatively charged particles play only a minor role. But ...

An electron is a subatomic particle usually found in orbit around an atomic nucleus. It is by definition said to have one unit of negative electrical charge. Current is nothing more than electrons in ...

An atom is the smallest unit of an element that retains its chemical properties. It is made of protons, neutrons, and electrons. (Image: M ...
