A 1906 proposal to change to electrion failed because Hendrik Lorentz preferred to keep electron. [25] [26] The word electron is a combination of the words electric and ion. [27] The suffix -on which is now used to designate other subatomic particles, such as a proton or neutron, is in turn derived from electron. [28] [29]
Electron was originally built for Atom [5] and is the main GUI framework behind several other open-source projects including GitHub Desktop, Light Table, [8] Visual Studio Code, WordPress Desktop, [9] and Eclipse Theia.
Electron is a two-stage, partially reusable orbital launch vehicle developed by Rocket Lab, an American aerospace company with a wholly owned New Zealand subsidiary. [ 14 ] [ 15 ] Servicing the commercial small satellite launch market, [ 16 ] it is the third most launched small-lift launch vehicle in history.

In particle physics, the electron mass (symbol: m e) is the mass of a stationary electron, also known as the invariant mass of the electron. It is one of the fundamental constants of physics . It has a value of about 9.109 × 10 −31 kilograms or about 5.486 × 10 −4 daltons , which has an energy-equivalent of about 8.187 × 10 −14 joules ...
The elementary charge, usually denoted by e, is a fundamental physical constant, defined as the electric charge carried by a single proton (+1 e) or, equivalently, the magnitude of the negative electric charge carried by a single electron, which has charge −1 e.
The classical electron radius is a combination of fundamental physical quantities that define a length scale for problems involving an electron interacting with electromagnetic radiation. It links the classical electrostatic self-interaction energy of a homogeneous charge distribution to the electron's relativistic mass-energy.
Any electron beam would collide with some residual gas atoms within the Crookes tube, thereby ionizing them and producing electrons and ions in the tube (space charge); in previous experiments this space charge electrically screened the externally applied electric field. However, in Thomson's Crookes tube the density of residual atoms was so ...
