Qhov nruab nrab silicon atom muaj kaum plaub protons, kaum plaub electrons, thiab feem ntau muaj 14 neutrons. Qhov no yog ib daim duab ntawm silicon atom. Qhov no qhia tau hais tias 14 protons hauv lub nucleusthiab qhov twg 14 electrons nyob. Plaub lub tshuab hluav taws xob, tseem ceeb hauv ntsuab, uas nyob rau hauv lub nplhaib sab nrauv yog lub valence electrons.
Dab tsi yog subatomic hais ntawm silicon?
Silicon muaj 14 protons, 14 neutrons, thiab 14 electrons.
Ob hom subatomic hais nyob qhov twg?
Nyob hauv nruab nrab ntawm txhua lub atom yog lub nucleus. Lub nucleus muaj ob hom subatomic hais, protons thiab neutrons. Cov protons muaj cov nqi hluav taws xob zoo thiab cov neutrons tsis muaj hluav taws xob. Ib yam thib peb ntawm subatomic particle, electrons, txav ib ncig ntawm lub nucleus.
Electrons nyob rau hauv silicon nyob qhov twg?
Thaum peb sau cov kev teeb tsa peb yuav muab tag nrho 14 electrons nyob rau hauv orbitals nyob ib ncig ntawm lub nucleus ntawm Silicon atom. Hauv kev sau cov khoom siv hluav taws xob rau Silicon thawj ob lub tshuab hluav taws xob yuav mus rau hauv 1s orbital. Txij li thaum 1s tuaj yeem tuav ob lub electrons tom ntej no 2 electrons rau Silicon mus rau hauv 2s orbital.
Koj pom cov subatomic li cas?
Lub cim rau lub atom tuaj yeem sau los qhia nws cov lej loj nyob rau sab saum toj, thiab nws tus lej atomic hauv qab. Txhawm rau xam cov lej ntawm cov subatomic hais hauv ib lub atom, siv nwsatomic naj npawb thiab huab hwm coj: tus naj npawb ntawm protons=atomic naj npawb . number of electrons=atomic tooj.

Editorials feem ntau yog luam tawm ntawm nplooj ntawv nplooj siab, hu ua nplooj ntawv kho, uas feem ntau sau cov ntawv rau tus editor los ntawm cov tswv cuab ntawm pej xeem; nplooj ntawv tawm tsam nplooj ntawv no yog hu ua nplooj ntawv op-ed thiab nquag muaj cov lus xav (li no lub npe xav daim) los ntawm cov kws sau ntawv tsis ncaj qha koom nrog … Lub hom phiaj ntawm kev sau ntawv hauv xov xwm yog dab tsi?
Nyob rau hauv c ++ cov kev qhia tshwj xeeb siv tau rau qhov twg hauv qab no?
Kev piav qhia: Cov kev qhia tshwj xeeb tuaj yeem siv tau rau cov tswv cuab cov ntaub ntawv thiab cov haujlwmvim tias lawv yuav tsum nkag mus rau sab nraud ntawm qhov thaiv. 4. Yuav ua li cas nkag tau rau hauv qab no yog siv tau? Kev piav qhia:
