Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Kupfuura: Huwandu husingachinji hweelektroni hunenge huri 9.109×10−31 makirogiramu, kana kuti 5.489×10−4 maatomic mass units. Zvichienderana nomutemo waEinstein wokukosha kwesimba, uremu uhwu hunoenzana nesimba rokuzorora re0.511 MeV. Chiyero chiri pakati peboka reproton nereerekitironi chinenge 1836. Kuyerwa kwenyeredzi kunoratidza kuti chiyero cheproton-kune-electron chakagara chakaenzana, sezvinotsanangurwa neStandard Model, kwehafu yezera rechisiko chose. Maerekitironi ane magetsi emagetsi e -1.602 × 10−19 coulombs, ayo anoshandiswa seyuniti yakaenzana yemari yezvikamu zveatomu, uye inonziwo mutero wekutanga. Uyu mutoro wepakutanga une kusava nechokwadi kwakaenzana kwe2.2×10−8. Mukati memiganhu yokutaura kwokuedza, mubhadharo weelektroni wakafanana nomubhadharo weproton, asi nechiratidzo chakapesana. Sezvo chiratidzo e chichishandiswa nokuda kwemutoro wepakutanga, elektroni inowanzoratidzirwa na e−, apo chiratidzo chokubvisa chinoratidza mutoro wakashata. Positron inoratidzirwa ne e+ nokuti ine zvinhu zvakafanana ne electron asi ine positive kwete negative charge. Electron ine intrinsic angular momentum kana kuti spin ye 1/2. Ichi chivakwa chinowanzotsanangurwa nekutaura nezve elektroni se spin-1/2 particle. Nokuda kwezvikamu zviduku zvakadai spin magnitude i √3/2 ħ. nepo mugumisiro wokuyerwa kwepurojekiti ye spin pane chero axis ingangova ±ħ/2. Kuwedzera pakutenderera, elektroni ine simba remagineti riri mukati mayo riri parutivi pemutsetse wayo wokutenderera. Inenge yakaenzana neBohr magneton imwe, iyo inogara iripo yemuviri yakaenzana ne9.27400915(23) × 10−24 joules pa tesla. Nzira iyo spin inotarisa nayo simba rinenge richiita kuti electron iite sechinhu chinonzi helicity. Electron haina chimiro chinozivikanwa uye inofungidzirwa kuti inonzi point particle ine point charge uye isina nzvimbo. Nyaya yeradius yeelectron idambudziko rakaoma refizikisi yemazuva ano. Kubvumirwa kwefungidziro yezera rinogumira...  Mubvunzo: Denderedzwa rechinhu chacho chii?
