Electron (formerly known as Atom Shell[ 5]) is a free and open-source software framework developed and maintained by OpenJS Foundation. [ 6] The framework is designed to create desktop applications using web technologies (mainly HTML, CSS and JavaScript, although other technologies such as front-end frameworks and WebAssembly are possible) that ...
The electron ( e−, or β− in nuclear reactions) is a subatomic particle with a negative one elementary electric charge. [ 13 ] Electrons belong to the first generation of the lepton particle family, [ 14 ] and are generally thought to be elementary particles because they have no known components or substructure. [ 1 ]
Flight 26 was the first Electron flight to attempt a full catch recovery using a mid-air helicopter catch. "Scout's Arrow" was the first suborbital launch of the rocket. In July 2019, Rocket Lab expected to have launches every two weeks in 2020. [ 1] In June 2020, with a new Electron launch vehicle built every 18 days, Rocket Lab was planning ...
Electron configuration. In atomic physics and quantum chemistry, the electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals. [ 1] For example, the electron configuration of the neon atom is 1s2 2s2 2p6, meaning that the 1s, 2s, and 2p subshells are occupied by ...
J. J. Thomson. Sir Joseph John Thomson OM FRS [ 1] (18 December 1856 – 30 August 1940) was a British physicist and Nobel Laureate in Physics, credited with the discovery of the electron, the first subatomic particle to be found. In 1897, Thomson showed that cathode rays were composed of previously unknown negatively charged particles (now ...
0.510 998 950 69(16) . [ 3] MeV. In particle physics, the electron mass (symbol: me) 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 ...

The mass-to-charge ratio ( m / Q) is a physical quantity relating the mass (quantity of matter) and the electric charge of a given particle, expressed in units of kilograms per coulomb (kg/C). It is most widely used in the electrodynamics of charged particles, e.g. in electron optics and ion optics .
