Ions raug tsim thaum atoms poob lossis nce electrons txhawm rau ua kom tiav txoj cai octet thiab muaj tag nrho cov valence electron shells. Thaum lawv poob electrons, lawv ua tau zoo thiab muaj npe cations. Thaum lawv tau txais electrons, lawv raug nqi tsis zoo thiab muaj npe hu ua anions.
Tom qab ntawd, ib tus tuaj yeem nug, dab tsi yog ob txoj hauv kev ua ion tuaj yeem ua tau?
Ions yog tsim los ntawm kev sib ntxiv ntawm electrons rau, los yog tshem tawm ntawm electrons los ntawm, nruab nrab atoms los yog molecules los yog lwm yam ions ; los ntawm kev sib xyaw ions nrog rau lwm cov khoom; los yog los ntawm rupture ntawm covalent daim ntawv cog lus ntawm ob atoms zoo li ntawd ob leeg ntawm cov electrons ntawm daim ntawv cog lus yog tshuav nyob rau hauv koom nrog ib tug ntawm cov
Tom qab ntawd, lo lus nug yog, ua li cas koj thiaj paub tias tus nqi them nqi dab tsi? Cov them nqi ntawm ib lub ntsiab yog sib npaug rau tus naj npawb ntawm protons rho tawm cov xov tooj ntawm electrons. Tus naj npawb ntawm protons yog sib npaug rau atomic naj npawb ntawm cov keeb muab nyob rau hauv lub periodic rooj. Tus naj npawb ntawm electrons yog sib npaug rau tus lej atomic rho tawm nqi ntawm atom.
Hais txog qhov no, ob hom ions yog dab tsi thiab lawv tsim li cas?
Ib ion yog tsim los ntawm kev poob lossis nce ntawm electrons los ntawm ib qho atom, yog li nws muaj ib tug tsis sib npaug ntawm electrons thiab protons. Piv txwv li: Sodium ion Na+, magnesium ion Mg2+, tshuaj chloride ion Cl–, thiab oxide ion O2–. Nyob ntawd yog ob hom ions : cations.
Dab tsi yog qhov zoo ion hu ua?
Ib ion yog ib tug atom los yog pawg ntawm atoms uas tus naj npawb ntawm electrons tsis sib npaug zos rau tus naj npawb ntawm protons. Thaum lub atom nce electrons, qhov no ua rau a tsis zoo nqi. Hom no ion yog hu ua ib anion. Thaum lub atom poob electrons, qhov no ua rau a zoo nqi. A zoo them ion yog hu ua ib cation.

Yuav ua li cas koj thiaj paub yog tias koj lub tsev nyob rau hauv lub dab dej?
Ntawm no yog 7 lub cim qhia ntau tshaj plaws hauv lub dab dej yuav tshwm sim: Ib puag ncig kev nyuaj siab nyob rau hauv lub ntiaj teb: Localized subsidence los yog kev nyuaj siab nyob txhua qhov chaw ntawm lub tsev: Lub pas dej ncig (los yog lub pas dej loj, tob): Lub hauv paus daws teeb meem: Kev tawg ntawm txoj kev lossis pavement : Cia li poob ntawm qhov dej hauv qhov chaw:
Koj tuaj yeem ua li cas yog tias koj tsis paub tias txheej twg yog nyob rau hauv cov txheej txheem rho tawm?
Koj tuaj yeem ua li cas yog tias koj tsis paub tias txheej twg yog nyob rau hauv cov txheej txheem rho tawm? Tso dej me me rau hauv lub caj dab ntawm qhov sib cais funnel. Ua tib zoo saib nws: yog tias nws tseem nyob hauv txheej txheej sab saud, txheej txheej ntawd yog txheej dej
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
Yuav ua li cas koj paub yog tias koj fontanelle yog bulging?
Cov fontanelles yuav tsum xav tias khov thiab me ntsis nkhaus sab hauv rau qhov kov. Ib qho kev nruj lossis bulging fontanelle tshwm sim thaum cov kua dej tsim hauv lub hlwb lossis lub hlwb o, ua rau muaj zog ntxiv hauv pob txha taub hau. Thaum tus menyuam mos quaj, pw, lossis ntuav, cov fontanelles yuav zoo li lawv bulping
Cov dej tsaws tsag puas tsim cov ions tsis zoo?
Txawm li cas los xij, dej hauv kev txav ua rau muaj ntau yam tsis zoo ions, nqa ntau lub zog thiab qhov tseem ceeb. Cov ions tsis zoo yog cov ntxhiab tsw, tsis qab, thiab tsis pom cov molecules uas peb nqus tau ntau hauv qee qhov chaw xws li dej hiav txwv tab sis kuj roob, thiab dej tsaws tsag
