Cov tus lej atomic tshwj xeeb txheeb xyuas cov khoom siv tshuaj lom neeg. Nws yog zoo tib yam rau tus nqi tus lej ntawm lub nucleus. Nyob rau hauv ib qho uncharged atom , cov atomic number yog kuj sib npaug mus rau tus lej ntawm electrons. Qhov sum ntawm tus lej atomic Z thiab tus lej ntawm neutrons N muab cov pawg naj npawb A ib atom.
Hauv qhov no, tus lej atomic ntawm ib lub caij sib npaug yog dab tsi?
Cov atomic naj npawb ntawm cov khoom yog sib npaug tus tus lej ntawm protons nyob rau hauv lub nucleus. Ib keeb yog daim ntawv purest ntawm ib yam khoom. Thaum muab faib, nws ua rau loj tus lej ntawm zoo tib yam atoms - xav tias tsis muaj isotopes nyob ntawd. Atoms muaj peb yam tseem ceeb hais: protons, neutrons thiab electrons.
Tsis tas li ntawd, tus lej atomic puas sib npaug ntawm cov electrons? Cov tus lej ntawm protons nyob rau hauv lub nucleus atom yog sib npaug mus rau tus lej atomic (Z). Cov tus naj npawb ntawm electrons nyob rau hauv nruab nrab atom yog sib npaug mus rau tus lej ntawm protons. Cov pawg naj npawb ntawm atom (M) yog sib npaug mus rau lub sum ntawm cov tus lej ntawm protons thiab neutrons nyob rau hauv lub nucleus.
Yog li ntawd, tus lej atomic sawv cev li cas?
Cov atomic tooj sawv cev los yog sawv cev rau tus kheej ntawm ib qho tshuaj lom neeg. Nws yog feem ntau txhais raws li tus tus lej los yog protons tam sim no nyob rau hauv ib atom ntawm ib lub ntsiab, uas kuj yog sib npaug rau cov tus lej ntawm electrons.
Vim li cas tus lej atomic sib npaug rau protons?
Cov atomic naj npawb sib npaug tus nqi ntawm lub nucleus. Nws kuj yog li ntawd sib npaug tus tus lej ntawm protons nyob rau hauv lub nucleus thiab sib npaug tus lej tus lej ntawm electrons hauv nruab nrab atom . Cov tus lej atomic muaj lub cim Z.

Yuav daws qhov tsis sib npaug ntawm cov kab sib npaug thiab cov kab sib npaug sib npaug li cas?
Kev daws qhov tsis sib npaug ntawm qhov sib npaug yog zoo ib yam li kev daws cov kab sib npaug. Qhov sib txawv tseem ceeb yog koj tig lub cim tsis sib xws thaum faib lossis muab faib los ntawm tus lej tsis zoo. Graphing linear inequalities muaj ob peb qhov sib txawv ntxiv. Qhov uas yog qhov ntxoov ntxoo muaj xws li qhov tseem ceeb uas qhov kev tsis sib xws ntawm cov kab tawm muaj tseeb
Puas yog txhua qhov sib npaug sib npaug sib npaug?
Thawj qhov sib npaug sib npaug yog qhov tseeb yog tias nws muaj kev txuag kom muaj nuj nqis. Piv txwv li, qhov sib npaug sib cais yeej ib txwm muaj tseeb, txij li lub ntsiab lus lawv yog ntawm daim ntawv: M(y) + N(t) = 0, yog li ϕ(t, y) = A(y) + B(t) yog a khaws cia kom muaj nuj nqis
Dab tsi yog cov lej suav tag nrho cov lej suav lej thiab lej lej?
Cov lej tiag yog feem ntau muab faib ua cov lej tsis sib haum xeeb thiab tsis sib haum xeeb. Cov zauv rational suav nrog tag nrho cov lej thiab feem. Txhua tus lej tsis zoo thiab tag nrho cov lej ua rau cov lej suav. Tag nrho cov lej suav nrog txhua tus lej ntuj thiab xoom
Koj ua li cas sib npaug tshuaj sib npaug nrog cov lej oxidation?
Hauv txoj kev oxidation naj npawb, koj txiav txim siab oxidation tooj ntawm tag nrho cov atoms. Tom qab ntawd koj muab cov atoms uas tau hloov los ntawm cov lej me me. Koj tab tom ua tag nrho cov poob ntawm electrons sib npaug rau tag nrho qhov nce ntawm electrons. Tom qab ntawd koj sib npaug ntawm cov atoms
Dab tsi yog qhov sib txawv ntawm cov kab lus sib npaug thiab qhov sib npaug sib npaug?
Cov kab lus sib npaug muaj qhov muaj txiaj ntsig zoo ib yam tab sis tau nthuav tawm nyob rau hauv ib hom ntawv sib txawv uas siv cov khoom ntawm cov lej xws li ax + bx = (a + b) x yog cov kab lus sib npaug. nruj me ntsis, lawv tsis yog 'sib npaug', yog li peb yuav tsum siv 3 kab sib luag hauv 'sib npaug' es tsis yog 2 raws li qhia ntawm no
