An electron is a subatomic particles of spin 1/2. It couples with photons and, thus, is electrically charged. It is a lepton with a rest mass of 9.109 * 10 − 31kg and an electric charge of − 1.602 * 10 − 19 C, which is the smallest known charge possible for an isolated particle (confined quarks have fractional charge).... | <urn:uuid:e1790b63-dd2a-43d8-ae60-c3a435647df2> | 3.859375 | 352 | Knowledge Article | Science & Tech. | 58.2225 | 100 |
