Piav: Rau lub cov ntsiab lus hauv kem 1, 2 thiab 13-18 atoms nyob rau hauv lub tib kem muaj cov ib yam Tus nqi ntawm cov hluav taws xob sab nraud, hu ua valence electrons. Cov kem ntawm lub atom kuj muaj feem xyuam rau tus nqi ntawm daim ntawv cog lus atom ua tau koom nrog tab sis qhov no yog tsis yooj yim li.
Yog li ntawd, vim li cas cov ntsiab lus nyob hauv tib kem?
Txhua kem hu ua pab pawg. Cov cov ntsiab lus nyob rau hauv txhua pab pawg muaj cov ib yam tus naj npawb ntawm cov electrons nyob rau sab nrauv orbital. Cov electrons sab nraud no kuj hu ua valence electrons. Lawv yog cov khoom siv hluav taws xob koom nrog cov tshuaj sib txuas nrog lwm yam cov ntsiab lus.
Ib tug kuj yuav nug, dab tsi ua cov ntsiab lus nyob rau hauv ib kab muaj sib xws? Lub sij hawm nyob rau hauv lub periodic table yog a kab ntawm chemical cov ntsiab lus . Tag nrho cov ntsiab lus hauv kab muaj tib tus naj npawb ntawm electron plhaub.
Kuj Paub, dab tsi ua rau tag nrho cov ntsiab lus nyob rau hauv ib kab ntsug ntawm lub sij hawm lub sij hawm muaj nyob rau hauv ntau?
Kev npaj ntawm lub daim ntawv qhia hnub ua rau peb pom qee qhov sib txawv ntawm cov atoms. Cov kab ntsug (paub) ntawm cov periodic table yog npaj li ntawd tag nrho nws cov ntsiab lus muaj tib tus naj npawb ntawm valence electrons. Txhua yam nyob rau hauv ib tug tej yam pab pawg neeg yog li qhia zoo xws li cov khoom.
Vim li cas cov ntsiab lus tau muab tso rau hauv kab thiab kab?
Cov tshuaj cov ntsiab lus yog npaj nyob rau hauv kev txiav txim ntawm nce atomic tooj. Kab rov tav kab hu ua lub sij hawm thiab ntsug kab hu ua pawg. Cov ntsiab lus nyob rau hauv tib pab pawg muaj cov tshuaj zoo sib xws. Qhov no yog vim lawv muaj tib tus lej ntawm cov khoom siv hluav taws xob sab nraud thiab tib qhov valency.

Dab tsi organelle suav hais tias yog lub Hoobkas vim tias nws siv rau hauv raw?
Chloroplast tig hnub ci, carbon dioxide, thiab dej rau hauv cov zaub mov (qabzib). Dab tsi organelle raug suav hais tias yog 'lub Hoobkas', vim tias nws siv cov khoom siv raw thiab hloov mus rau cov khoom lag luam ntawm tes uas tuaj yeem siv los ntawm lub xovtooj? Cell membrane tiv thaiv lub cell; tswj qhov nkag mus rau hauv thiab tawm ntawm tes, kev sib txuas lus
Lub Tuam Tsev txhais li cas thaum nws hais tias kuv ntseeg tias qhov zoo rau nyuj yog qhov zoo rau kev lag luam?
Lub tuam tsev txhais tau hais tias yog cov nyuj muaj kev hwm thiab kho tau zoo, lawv yuav yooj yim dua los tuav uas yuav ua rau cov txheej txheem zoo dua rau txhua tus neeg koom tes
Yuav ua li cas koj paub yog hais tias ib yam khoom tshiab yog tsim nyob rau hauv ib tug tshuaj sib npaug?
Muaj cov cim qhia tias muaj tshuaj lom neeg tshwm sim. Npuas daim ntawv, ib tug roj yog muab tawm, thiab lub beaker tau kub heev. Lub cim tseem ceeb tshaj plaws uas muaj tshuaj lom neeg tshwm sim yog kev tsim cov tshuaj tshiab. Cov khoom tshiab yog cov pa roj carbon, lub nkig dub, thiab dej vapor, roj tsis muaj xim
Nws txhais li cas hais tias ntawm tib neeg peb lub cev yog kev cob qhia?
Teb sab saum toj. Xwm yog qhov peb xav tias ua ntej xaim cuam tshuam los ntawm cov noob caj noob ces thiab los ntawm lwm yam kab mob lom. Nurture yog coj raws li kev cuam tshuam ntawm lwm yam tom qab conception. Piv txwv li, cov khoom ntawm kev raug thiab cov kev paub ntawm kev kawm ntawm ib tug neeg
Nws txhais li cas hais tias ib yam dab tsi nyob rau hauv mechanical equilibrium?
Nyob rau hauv classical mechanics, ib tug particle yog nyob rau hauv mechanicalequilibrium yog hais tias lub net quab yuam ntawm cov particle yog xoom. Byextension, lub cev lub cev ua los ntawm ntau qhov chaw yog inmechanical equilibrium yog hais tias lub net quab yuam ntawm txhua qhov ntawm nws tus kheej qhov chaw yog xoom
