Cov ntsiab lus. 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).
Ntawm no, koj pom cov protons electrons thiab neutrons li cas?
Kev piav qhia: Koj tuaj yeem rho tawm tus lej atomic los ntawm tus lej loj thiaj li yuav nrhiav tus lej ntawm neutrons . Yog hais tias lub atom yog nruab nrab, tus naj npawb ntawm electrons yuav muab sib npaug rau tus naj npawb ntawm protons.
Ib yam li ntawd, lub hom phiaj ntawm protons neutrons thiab electrons yog dab tsi? Txhua lub ntsiab muaj qhov sib txawv ntawm tus nqi protons . Neutrons muaj lub luag haujlwm rau kev sib txuas nrog protons nyob rau hauv lub nucleus ua ke kom tuav los ntawm lub zog muaj zog. Ntau dhau lawm neutrons nyob rau hauv ib tug atom yuav ua rau radioactive decay vim lub neutrons ' quab yuam overpowering lub zog muaj zog. Hluav taws xob yog cov weirdest hais.
Tom qab ntawd, protons neutrons thiab electrons ua los ntawm dab tsi?
Protons yog ua nce ib tug down quark thiab ob nce quarks. Neutrons yog ua los ntawm ob tug down quarks thiab ib tug up quark. Hluav taws xob tsis yog ua los ntawm dab tsi. Hluav taws xob yog ib qho tseem ceeb raws li peb paub.
Yuav ua li cas koj paub tus naj npawb ntawm electrons?
Cov tus naj npawb ntawm electrons nyob rau hauv ib tug nruab nrab atom yog sib npaug rau cov tus lej ntawm protons. Qhov loj tus lej ntawm lub atom (M) yog sib npaug rau cov sum tus lej ntawm protons thiab neutrons nyob rau hauv lub nucleus. Cov tus lej ntawm neutrons yog sib npaug rau qhov sib txawv ntawm qhov loj tus lej ntawm lub atom (M) thiab lub atomic tus lej (Z).

Sociobiology yog dab tsi thiab dab tsi yog qhov kev thuam loj ntawm nws?
Ib feem ntawm sociobiology cuam tshuam nrog kev coj tus cwj pwm tsis zoo feem ntau. Cov neeg thuam tau hais tias daim ntawv thov ntawm sociobiology no yog ib hom kev txiav txim siab caj ces thiab nws ua tsis tau raws li qhov nyuaj ntawm tib neeg tus cwj pwm thiab qhov cuam tshuam ntawm ib puag ncig ntawm tib neeg txoj kev loj hlob
Dab tsi yog thawj kauj ruam ntawm proton proton saw?
Proton-proton chain reaction. Thawj kauj ruam nyob rau hauv tag nrho cov ceg yog fusion ntawm ob protons rau hauv deuterium. Raws li cov protons fuse, ib tug ntawm lawv undergoes beta ntxiv rau lwj, hloov mus rau hauv ib tug neutron los ntawm emitting ib tug positron thiab ib tug electron neutrino
Qhov txawv ntawm qhov loj ntawm ib tug proton thiab qhov loj ntawm ib tug electron yog dab tsi?
Protons thiab neutrons muaj kwv yees li qub, tab sis lawv yog ob qho tib si loj dua li cov hluav taws xob (kwv yees li 2,000 npaug loj li electron). Tus nqi zoo ntawm ib qho proton yog sib npaug hauv qhov loj rau qhov tsis zoo ntawm tus electron
Tus nqi thiab qhov loj ntawm proton thiab neutron piv li cas?
Yuav ua li cas tus nqi thiab qhov loj ntawm ib tug neutron piv rau tus nqi thiab loj ntawm ib tug proton? Lawv cov huab hwm coj yuav luag sib npaug, tab sis cov protons muaj cov nqi zoo thiab cov neutrons muaj cov nqi nruab nrab. Yog tias koj poob ib qho hluav taws xob ces koj tseem tshuav tus nqi zoo dua li tus nqi tsis zoo
Thaum twg cov proton neutron thiab electron nrhiav tau?
1932 Kuj paub, leej twg nrhiav tau electron proton thiab neutron xyoo twg? Teb 1: Kev sim los ntawm J.J. Thomson nyob rau hauv 1897 coj mus rau lub nrhiav pom ntawm ib qho tseem ceeb tsev thaiv ntawm qhov teeb meem ib puas xyoo dhau los, British physicist J.
