Fahimtar Ƙwayoyin Subatomic
A mafi sauƙi, abu ya ƙunshi atom, wanda a da ake tunanin shine mafi ƙanƙantar halittu marasa rabuwa. Duk da haka, farkon ƙarni na 20 ya kawo sauyi ga fahimtarmu tare da gano cewa atom ya ƙunshi ƙananan abubuwa: ƙananan ƙwayoyin halitta. Akwai manyan nau'ikan ƙwayoyin halitta guda uku waɗanda suka haɗa da tsarin atom: protons, neutrons, da electrons. Kowanne daga cikin waɗannan ƙwayoyin halitta yana da halaye na musamman kuma yana yin ayyuka daban-daban.
protons
Protons ƙwayoyin cuta ne masu caji masu kyau waɗanda suka rage a cikin ƙwayar zarra. Tare da nauyin da ya dace da naúrar yawan atomic guda ɗaya (amu), protons suna taka muhimmiyar rawa wajen bayyana asalin wani abu. Adadin protons, wanda aka sani da lambar atomic, yana ƙayyade wane abu ne kwayar zarra ke wakilta. Misali, kwayar zarra mai protons shida ita ce carbon, yayin da kwayar zarra mai protons takwas ita ce iskar oxygen. Girman proton da cajin suna da mahimmanci wajen tasiri ga halayen kwayar zarra da kuma halayen kwayar zarra gaba ɗaya.
Neutrons
Neutrons barbashi ne masu tsaka-tsaki a wutar lantarki, waɗanda kuma suke cikin ƙwayar atom. Duk da rashin wutar lantarki, neutrons suna da nauyin da ya yi daidai da protons, kusan 1 amu. Kasancewar neutrons yana ba da gudummawa sosai ga kwanciyar hankalin ƙwayar atom. Ana kiran abubuwan da ke da adadin proton iri ɗaya amma lambobi daban-daban na neutrons, suna nuna bambance-bambance a cikin halayensu na zahiri kamar kwanciyar hankali da halayyar rediyoaktif. Neutrons suna taka muhimmiyar rawa a cikin halayen nukiliya da kuma haɗa abubuwa masu nauyi a cikin taurari.

Sabanin protons da neutrons, electrons ƙananan ƙwayoyin cuta ne masu nauyin da ba su da yawa (kimanin 1/1836 na nauyin proton) da kuma cajin lantarki mara kyau. Elektrons suna kewaya tsakiya a yankuna da ake kira gajimare na electron ko kuma orbital na atomic, amma ainihin matsayinsu da ƙarfinsu ana sarrafa su ne ta hanyar ƙa'idodin makanikan quantum. Elektrons suna ƙayyade halayen sinadarai na atom da yadda yake hulɗa da sauran atoms, suna samar da haɗin gwiwa waɗanda suka ƙunshi ƙwayoyin halitta da mahadi.

Bayan protons, neutrons, da electrons, fannin kimiyyar lissafi na barbashi yana bincika ƙarin barbashi masu mahimmanci ta hanyar Tsarin Daidaitacce. Tsarin Daidaitacce ya rarraba barbashi masu ƙananan atom da aka sani zuwa ƙungiyoyi biyu: fermions da bosons. Fermions su ne barbashi masu ƙarfi, yayin da bosons su ne masu ɗaukar ƙarfi waɗanda ke shiga tsakani tsakanin barbashi masu ƙarfi.
Fermions
An ƙara raba fermions zuwa quarks da leptons. Quarks suna haɗuwa don samar da protons da neutrons. Akwai nau'ikan quarks guda shida: sama, ƙasa, fara'a, abin mamaki, sama, da ƙasa. Protons sun ƙunshi quarks guda biyu sama da ɗaya down quark, yayin da neutrons sun ƙunshi quarks guda biyu ƙasa da ɗaya down quark. Quarks suna da wani abu da ake kira color charge, kuma suna hulɗa ta hanyar ƙarfi mai ƙarfi, wanda gluons ke jagoranta.
Leptons sun haɗa da electrons, muons, tau barbashi, da neutrinos masu dacewa da su (electron neutrinos, muon neutrinos, da tau neutrinos). Baya ga electrons, sauran leptons suna shiga cikin hanyoyin samar da makamashi mai yawa da hanyoyin ruɓewa, kamar waɗanda aka lura a cikin masu haɓaka barbashi.
