A tus nqi tsis zoo xav muab nws cov electrons los ua nruab nrab yog li ntawd nws attracts positivecharge mus rau nws. Ntawm qhov tod tes, a tus nqi zoo yuav tsum tau electrons los ua nruab nrab, yog li ntawd nws txav mus rau tus nqi tsis zoo.
Khaws qhov no hauv kev xav, vim li cas qhov tsis zoo thiab qhov zoo nyiam?
Ob tug electrons yuav nyiam ib leeg vim ob leeg muaj a tsis zoo hluav taws xob. Ob tug protons kuj tseem yuav tawm tsam ib leeg vim lawv ob leeg muaj ib qho zoo nqi. Ntawm qhov tod tes, electrons thiab protons yuav nyiam rau ib leeg vim lawv qhov tsis sib xws.
Tsis tas li ntawd, yuav ua li cas thaum cov nqi zoo thiab qhov tsis zoo tuaj ua ke? Qhov zoo qhov chaw nyiam tsis zoo hais (xws li electrons) thiab tawm tsam zoo ions, thiab qhov ntawd yog qhov tseeb rau tsis zoo nto. Qhov no acceleration ntawm nqi ua rau "avalanche" ntawm raug them objectsaway ntawm qhov chaw, thiab ntau raug them cov khoom ntsib andrecombine raws li qhov tshwm sim ntawm qhov tshwm sim.
Ua raws li qhov kev pom no, puas muaj qhov zoo thiab qhov tsis zoo nyiam?
Ob hom hluav taws xob no nqi - zoo thiab tsis zoo - yog hais tias yog opposite hom nqi . Thiab ua raws li peb lub hauv paus ntsiab lus ntawm nqi kev sib cuam tshuam, zoo raug them khoom yuav nyiam ib yam tsis zoo raug them khoom. Cov khoom nrog zoo li nqi ntxeev siab rau ib leeg.
Vim li cas cov nqi sib txawv nyiam?
Zoo li nqi repel, tsis zoo li nqi txaus nyiam Txij li thaum cov hluav taws xob me me thiab sib zog dua li aproton, thaum lawv nyob nyiam rau txhua tus lwm yam vim lawv tsis nyiam nqi , cov electron feem ntau ua rau lawv txav. Qhov no yog vim hais tias cov protons muaj ntau dua thiab nyuaj rau txav mus.

Vim li cas peb thiaj li kho cov coefficients thaum ntsuas cov tshuaj sib npaug thiab tsis yog cov ntawv sau npe?
Thaum koj hloov cov coefficients, koj tsuas yog hloov tus naj npawb ntawm cov molecules ntawm cov khoom tshwj xeeb. Txawm li cas los xij, thaum koj hloov cov ntawv sau npe, koj tab tom hloov cov tshuaj nws tus kheej, uas yuav ua rau koj qhov sib npaug tshuaj tsis raug
Vim li cas lub cube cag ntawm tus lej tsis zoo yog tus lej tsis zoo?
Tus lej tsis zoo lub voos xwmfab hauv paus yuav tsis zoo Txij li qhov ntsuas tus lej txhais tau tias tsa nws mus rau lub zog thib 3 - uas yog khib - lub voos xwmfab ntawm cov lej tsis zoo yuav tsum yog qhov tsis zoo. Thaum lub qhov hluav taws xob tawm (xiav), qhov tshwm sim tsis zoo. Thaum lub qhov hluav taws xob qhib (daj), qhov tshwm sim yog qhov zoo
Vim li cas tsis zoo thiab tsis zoo yog qhov zoo?
Thaum koj muab qhov tsis zoo los ntawm qhov tsis zoo koj tau txais qhov zoo, vim tias ob lub cim tsis zoo raug muab tso tseg
Vim li cas protons thiab electrons tsis nyiam ib leeg?
Protons thiab electrons lo rau ib leeg ntau npaum li lawv ua tau, tab sis lub zog kinetic thiab quantum mechanics ua kom lawv tsis txhob tuav. Protons thiab electrons yog attracted rau ib leeg vim hais tias qhov zoo hluav taws xob nqi ntawm lub proton yog attracted rau qhov tsis zoo nqi ntawm lub electron
Vim li cas cov kab mob Gram tsis zoo tshwm liab liab thaum cov kab mob Gram zoo pom ntshav liab?
Gram zoo hlwb stain ntshav vim lawv cov peptotidoglycan txheej yog tuab txaus, txhais tau tias tag nrho cov kab mob Gram zoo yuav khaws lawv cov stain. Gram tsis zoo hlwb stain liab vim lawv muaj ib tug nyias peptidoglycan phab ntsa, thiab lawv yuav tsis khaws ib yam ntawm cov ntshav stain los ntawm crystal violet
