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.

Dab tsi yog qhov txawv ntawm Marine West Coast huab cua thiab dab tsi yog lub luag haujlwm rau cov yam ntxwv ntawd?
Cov ntsiab lus ntawm Marine West Coast Qhov kev nyab xeeb ntawm cov yam ntxwv tseem ceeb yog lub caij ntuj sov me me thiab lub caij ntuj no thiab cov nag lossis daus txhua xyoo. Qhov ecosystem no muaj kev cuam tshuam loj heev los ntawm nws qhov ze rau ntawm ntug dej hiav txwv thiab roob. Nws yog qee zaum hu ua huab cua sab hnub poob ntug dej hiav txwv lossis dej hiav txwv huab cua
Cov yam ntxwv ntawm cov ntaub ntawv twg yog qhov ntsuas ntawm tus nqi uas cov ntaub ntawv muaj nuj nqis heev?
Variation: Ib qho kev ntsuas ntawm tus nqi uas cov ntaub ntawv muaj nuj nqis sib txawv. ? Kev faib tawm: Cov xwm txheej lossis cov duab ntawm kev sib kis ntawm cov ntaub ntawv hla ntau qhov tseem ceeb (xws li tswb-puab). ? Outliers: Cov qauv piv txwv uas nyob deb heev ntawm feem ntau ntawm lwm cov qauv nqi
Qhov twg ntawm cov no yog tus yam ntxwv ntawm txhua yam muaj sia?
Cov yam ntxwv no yog lub koom haum ntawm tes, kev yug me nyuam, metabolism, homeostasis, heredity, teb rau stimuli, kev loj hlob thiab kev loj hlob, thiab adaptation los ntawm evolution. Qee yam, xws li tus kab mob, pom tsuas yog qee yam ntawm cov yam ntxwv no thiab yog li ntawd, tsis muaj sia nyob
Dab tsi ntawm lub cev nta yog cov yam ntxwv ntawm cov ntug dej hiav txwv ntawm Texas?
Texas 'Gulf Coastal Plains yog sab hnub poob txuas ntxiv ntawm ntug hiav txwv tiaj tiaj txuas los ntawm Dej Hiav Txwv Atlantic mus dhau Rio Grande. Nws cov yam ntxwv dov mus rau toj roob hauv pes npog nrog kev loj hlob hnyav ntawm ntoo thuv thiab tawv ntoo txuas mus rau East Texas
Dab tsi yog cov yam ntxwv ntawm protons neutrons thiab electrons?
Proton - zoo; electron-tsis zoo; neutron - tsis muaj nqi. Tus nqi ntawm cov proton thiab electron yog tib yam nkaus tab sis txawv. Tib tus naj npawb ntawm protons thiab electrons raws nraim tshem tawm ib leeg hauv ib qho nruab nrab atom
