Protons muaj nyob rau hauv lub nucleus ntawm lub atom. Qhov no yog ib cheeb tsam me me, ntom ntom ntawm qhov nruab nrab ntawm lub atom. Protons muaj ib tug zoo hluav taws xob nqi ntawm ib tug (+1) thiab ib tug loj ntawm 1 atomic mass unit (amu), uas yog hais txog 1.67 × 10-27 kilograms.

Tsis tas li ntawd, cov khoom ntawm protons neutrons thiab electrons yog dab tsi?

Hluav taws xob yog ib hom subatomic particle uas muaj tus nqi tsis zoo. Protons yog ib hom subatomic particle nrog ib tug zoo nqi. Protons tau khi ua ke hauv ib qho atom lub nucleus vim yog lub zog muaj zog nuclear. Neutrons yog hom subatomic particle uas tsis muaj nqi (lawv nyob nruab nrab).

Ib sab saum toj no, dab tsi yog cov khoom ntawm electrons? Electrons muaj peb yam khoom tseem ceeb: nqi, pawg , thiab spin. Los ntawm kev txhais, tus nqi hluav taws xob ntawm ib qho hluav taws xob yog −1. Cov pawg ntawm ib qho hluav taws xob tau ntsuas thiab pom tias yog 9.109389 × 10 31 kilograms. Electrons kuj tig rau ntawm lawv cov axes ntau yam zoo ib yam li cov ntiaj chaw ua.

Ib tug kuj yuav nug, dab tsi yog lub zog ntawm ib tug neutron?

Qhov loj ntawm lub neutron yog 939.565 MeV/c. Neutrons yog ½ spin particles - fermionic txheeb cais. Neutrons yog cov khoom nruab nrab - tsis muaj hluav taws xob them nyiaj. Neutrons muaj lub sijhawm tsis yog xoom magnetic.

Dab tsi yog cov khoom ntawm 3 subatomic hais?

Protons, neutrons, thiab electrons yog cov peb lub ntsiab subatomic hais pom nyob rau hauv ib qho atom. Protons muaj qhov zoo (+) nqi. Ib txoj hauv kev yooj yim kom nco ntsoov qhov no yog kom nco ntsoov tias ob qho tib si proton thiab zoo pib nrog tsab ntawv "P." Neutrons tsis muaj hluav taws xob.
