Muaj peb lub subatomic hais: protons, neutrons thiab electrons. Ob ntawm subatomic hais muaj hluav taws xob tsub nqi: protons muaj tus nqi zoo thaum electrons muaj qhov tsis zoo.
Dab tsi subatomic particle ib txwm zoo?
Proton yog lub subatomic particle nrog rau tus nqi zoo. Neutrons yog hluav taws xob nruab nrab, thaum electrons raug nqi tsis zoo.
Particle twg yog qhov tsis zoo them nqi?
Electron: Ib qho teeb meem tsis zoo pom pom ncig los yog orbiting lub atomic nucleus. Ib tug electron, zoo li ib tug proton yog ib tug nqi particle, txawm hais tias opposite nyob rau hauv kos npe rau, tab sis tsis zoo li ib tug proton, ib tug electron muaj negligible atomic mass. Electrons tsis muaj atomic mass units rau tag nrho atomic hnyav ntawm ib atom.
Puas yog neutron yog qhov tsis zoo subatomic particle?
Neutron, nruab nrab subatomic particle uas yog ib feem ntawm txhua atomic nucleus tsuas yog hydrogen zoo tib yam. Nws muaj tsis muaj nqi hluav taws xob thiab qhov seem seem sib npaug 1.67493 × 10 - 27 kg-marginally ntau dua tshaj li ntawm cov proton tab sis ze li ntawm 1,839 npaug ntau dua li ntawm cov electron.
Puas yog qhov zoo them subatomic particle?
proton: Qhov zoo them subatomic particle ua ib feem ntawm lub nucleus ntawm lub atom thiab txiav txim siab tus naj npawb atomic ntawm ib lub caij. … neutron: Ib tug subatomic particle ua ib feem ntawm lub nucleus ntawm ib tug atom. Nws tsis muaj nqi. Nws yog sib npaug ntawm qhov hnyav rau ib qho proton lossis nws hnyav 1 amu.
