Cov txheeb ze pawg ntawm ib tug proton yog 1, thiab ib tug particle nrog a txheeb ze pawg me dua 1 muaj tsawg pawg . Vim lub nucleus muaj protons thiab neutrons, feem ntau ntawm cov pawg ntawm ib tug atom yog concentrated nyob rau hauv nws cov nucleus. Protons thiab electrons muaj hluav taws xob sib txawv nqi.
Ib yam li ntawd, tib neeg nug, tus nqi txheeb ze yog dab tsi?
Peb tuaj yeem hais tias cov no yog qhov tseem ceeb ntawm nqi . Txawm li cas los xij, kom yooj yim cov khoom yog peb hais tias ib qho hluav taws xob muaj -1 units nqi ces proton yuav muaj +1 units nqi . Cov naj npawb no hu ua cov nqi txheeb ze qhov twg -1 yog sib npaug rau -1.602 x 10^-19 Coulomb.
dab tsi muaj tus txheeb ze tus nqi ntawm 1+? Tshaj A'level: Protons thiab neutrons tsis yog qhov tseeb muaj raws nraim tib yam pawg - ob leeg ntawm lawv muaj ib pawg ntawm raws nraim 1 nyob rau hauv cov pa roj carbon-12 scale (qhov ntsuas ntawm qhov kwv tij Qhov loj ntawm atoms yog ntsuas).
Protons, neutrons thiab electrons.
| txheeb ze pawg | tus nqi txheeb ze | |
|---|---|---|
| proton | 1 | +1 |
| neutron | 1 | 0 |
| hluav taws xob | 1/1836 | -1 |
Nyob rau hauv no txoj kev, dab tsi yog qhov txheeb ze huab hwm coj thiab nqi ntawm ib tug electron?
Cov khoom ntawm sub-atomic hais
| Particle | kwv tij coob | kwv tij them nqi |
|---|---|---|
| Proton | 1 | +1 |
| Neutron | 1 | 0 |
| Hluav taws xob | -1 |
Tus nqi txheeb ze ntawm Proton yog dab tsi?
Proton , ruaj khov subatomic particle uas muaj qhov zoo nqi sib npaug hauv qhov loj rau ib chav tsev ntawm electron nqi thiab so pawg 1.67262 × 10−27 yog 1,836x pawg ntawm ib tug electron. Proton.

Dab tsi yog qhov txawv ntawm qhov pom tseeb qhov loj thiab qhov ntsuas qhov ntsuas qhov tseeb?
Dab tsi yog qhov txawv ntawm qhov pom tseeb thiab qhov tseeb? Pom meej qhov loj npaum li cas yog qhov ci ntawm lub hnub qub tshwm los ntawm lub ntiaj teb thiab nyob ntawm qhov ci thiab qhov deb ntawm lub hnub qub. Qhov loj npaum li cas yog qhov ci ntawm lub hnub qub yuav tshwm sim los ntawm tus qauv nyob deb
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
Dab tsi yog qhov pom tseeb qhov loj thiab qhov loj kawg nkaus?
Astronomers txhais lub hnub qub ci nyob rau hauv cov ntsiab lus ntawm qhov pom tseeb - qhov ci ntawm lub hnub qub tshwm los ntawm lub ntiaj teb - thiab qhov loj npaum li cas - lub hnub qub ci ci li cas ntawm qhov kev ncua deb ntawm 32.6 lub teeb xyoo, lossis 10 parsecs
Dab tsi yog qhov yuam kev loj tshaj plaws yog tias Irina ntsuas qhov ntev ntawm nws lub qhov rais li 3.35 feet qhov yuam kev loj tshaj plaws yog taw?
Kev daws: Qhov yuam kev loj tshaj plaws hauv kev ntsuas ntsuas tau txhais tias yog ib nrab ntawm qhov ntsuas ntsuas
Dab tsi yog qhov sib txawv ntawm qhov txheeb ze zaus thiab qhov xwm txheej txheeb ze?
Marginal txheeb ze zaus yog qhov piv ntawm cov lej ntawm qhov sib koom ua ke txheeb ze zaus hauv kab lossis kab thiab tag nrho cov ntaub ntawv muaj nuj nqis. Conditional txheeb ze zaus tus lej yog qhov sib piv ntawm qhov sib koom sib txheeb zaus thiab muaj feem cuam tshuam txog qhov sib txawv ntawm qhov sib txawv
