An electron has been turned into a spiralling wave of mass and charge, with the help of a laser. “Chirality, or handedness, ...

Charge is measured in coulombs (C). Since electrons are so small and one electron will not have much of an effect anywhere, it is more useful to refer to large groups of electrons. One coulomb of ...

The most significant type of interaction is simply between the charge of the ... in the energy of an electron in some experiment, they can work backwards and determine the mass of the virtual ...

Rutherford also put out the idea that there could be a particle with mass but no charge. He called it a neutron, and imagined it as a paired proton and electron. There was no evidence for any of ...
