CO OZNACZA SŁOWO ELECTRON
Elektron
Elektron jest cząstką subatomową z ujemnym podstawowym ładunkiem elektrycznym. Elektrony należą do pierwszego pokolenia rodziny leptonowych cząstek, i są ogólnie uważane za cząsteczki elementarne, ponieważ nie mają znanych składników lub podbudowy. Elektron ma masę, która wynosi około 1/1836 tego protonu. Właściwości mechaniczne kwantowe elektronu obejmują wewnętrzny moment pędu o wartości częściowej całkowitej w jednostkach ħ, co oznacza że jest fermionem. Zgodnie z zasadą wykluczenia Pauli, jako fermiany, nie ma dwóch elektronów, które mogą zajmować to samo państwo kwantowe. Elektrony posiadają również właściwości zarówno cząstek, jak i fali, a więc mogą zderzać się z innymi cząstkami i mogą być dyfrakcjonowane jak światło. Eksperymenty z elektronami najlepiej demonstrują tę dualność, ponieważ elektrony mają małą masę. Wiele zjawisk fizycznych obejmuje elektrony odgrywające istotną rolę, taką jak elektryczność, magnetyzm i przewodnictwo cieplne, a także uczestniczą w oddziaływaniu grawitacyjnym, elektromagnetycznym i słabym. Elektron w przestrzeni generuje pole elektryczne otaczające go. Elektron poruszający się względem obserwatora wytwarza pole magnetyczne.

CYTATY ZE SŁOWEM «ELECTRON»
Słynne cytaty i zdania ze słowem
electron.
The electron can no longer be conceived as a single, small granule of electricity; it must be associated with a wave, and this wave is no myth; its wavelength can be measured and its interferences predicted.
I always imagined myself somehow as an electron around some atom, and you're just, like, bouncing around and spinning. There was a never-ending supply of places to go, people to see, things to do, and fitting it all in became kind of an art.
We had to understand things like why the top quark was so heavy and the electron is so light. The Higgs is a big, important step.
In the 1920s, a generation before the coming of solid-state electronics, one could look at the circuits and see how the electron stream flowed. Radios had valves, as though electricity were a fluid to be diverted by plumbing. With the click of the knob came a significant hiss and hum, just at the edge of audibility.
In 1956 we observed the electron antineutrino.
We have learnt through experience that when an electrical ray strikes the surface of an atom, an electron, and in some circumstances a second and even a third electron, can be detached.
The removal of an electron from the surface of an atom - that is, the ionization of the atom - means a fundamental structural change in its surface layer.
My own interest in basic aspects of electron transfer between metal complexes became active only after I came to the University of Chicago in 1946.
You'd need a very specialized electron microscope to get down to the level to actually see a single strand of DNA.
According to well-known electrodynamic laws, an electron moving in a magnetic field is acted upon by a force which runs perpendicular to the direction of motion of the electron and to the direction of the magnetic field, and whose magnitude is easily determined.
