Duba wurin da ke ƙasa sannan ka amsa tambayar daga baya a cikin harshe ɗaya kamar yadda wurin yake:  Hanyar wucewa: Matsakaicin matsakaici na lantarki yana da kimanin 9.109 × 10-31 kilogram, ko 5.489 × 10-4 atomatik raka'a. Dangane da ka'idar Einstein na daidaiton taro-makamashi, wannan taro ya dace da makamashi mai hutawa na 0.511 MeV. Matsakaicin tsakanin taro na proton da na electron kusan 1836. Ma'aunin ilimin taurari ya nuna cewa rabon proton-to-electron yana da darajar iri ɗaya, kamar yadda aka annabta ta Tsarin Model, aƙalla rabin shekarun sararin samaniya. Lantarki suna da cajin lantarki na -1.602 × 10−19 coulombs, wanda aka yi amfani dashi azaman daidaitaccen cajin caji don barbashi na atomatik, kuma ana kiransa cajin asali. Wannan cajin na asali yana da daidaitattun daidaitattun daidaitattun 2.2 × 10−8. A cikin iyakokin daidaito na gwaji, cajin lantarki daidai yake da cajin proton, amma tare da alamar kishiya. Kamar yadda ake amfani da alama e don cajin farko, ana amfani da lantarki ta hanyar e -, inda alamar minus ke nuna cajin mara kyau. Ana nuna alamar positron ta hanyar e + saboda yana da kaddarorin iri ɗaya kamar na lantarki amma tare da caji mai kyau maimakon mara kyau. Wutar lantarki tana da ƙarfin angular na ciki ko juyawa na 1/2. Wannan kaddarorin yawanci ana bayyana ta hanyar komawa zuwa ga lantarki a matsayin mai juyawa-1/2 barbashi. Don irin waɗannan barbashi girman girman shine √ 3 / 2 ħ. yayin da sakamakon aunawar hasashen juyawa akan kowane axis zai iya zama ±ħ / 2 kawai. Baya ga juyawa, electron yana da lokacin magnetic na ciki tare da axis na juyawa. Yana da kusan daidai da ɗaya Bohr magneton, wanda shine daidaitattun ilimin lissafi daidai da 9.27400915 ((23) × 10−24 joules a kowace tesla. Gabatarwar juyawa dangane da ƙarfin lantarki yana bayyana dukiyar ƙwayoyin ƙwayoyin da aka sani da helicity. Ba a san lantarki ba kuma an ɗauka cewa yana da wani abu mai mahimmanci tare da cajin ma'ana kuma ba tare da wani yanki ba. Batun radius na lantarki shine matsala mai wuya na ilimin lissafi na zamani. Amincewa da hasashen na iyakacin radius...  Tambaya: Mene ne radius na abu?
