Qhov sib txawv tseem ceeb ntawm magnesium atom thiab magnesium ion yog magnesium atom muaj 12 electrons thiab yog ib hom tshuaj nruab nrab, hos magnesium ion muaj 10 electrons thiab yog hom tshuaj zoo.
Magnesium yog ib yam tshuaj nyob rau hauv lub sij hawm lub sij hawm ntawm cov khoom. Nws muaj 12 protons uas txiav txim siab nws tus lej atomic. Feem ntau, nyob rau hauv magnesium atom, tus naj npawb ntawm electrons zoo ib yam li cov protons. Thaum ionization, cov hluav taws xob sab nraud tuaj yeem tso tawm ntawm lub atom los ua magnesium ions. Qhov ruaj khov tshaj plaws ion ntawm magnesium yog magnesium ion nyob rau hauv lub xeev oxidation +2.
Magnesium yog dab tsi?
Magnesium yog ib yam tshuaj muaj atomic tooj 12. Lub cim tshuaj ntawm cov tshuaj no yog Mg. Feem ntau, magnesium tshwm sim raws li cov khoom grey-ci ci ntawm chav sov. Nws tshwm sim nyob rau hauv pawg 2, lub sij hawm 3 nyob rau hauv lub periodic table. Yog li ntawd, nws yog ib qho s-block element. Ntxiv mus, magnesium yog ib qho alkaline ntiaj teb hlau (pab pawg 2 tshuaj muaj npe hu ua alkaline ntiaj teb hlau). Lub teeb tsa hluav taws xob ntawm cov hlau no yog [Ne]3s2
Magnesium yog cov hlau hnyav, thiab nws muaj qhov qis tshaj plaws rau melting thiab boiling cov ntsiab lus ntawm alkaline ntiaj teb hlau. Cov hlau no tseem nkig thiab yooj yim undergoes tawg nrog rau shear bands. Thaum nws yog alloyed nrog aluminium, lub alloy yuav ductile heev.
Magnesium Atom yog dab tsi?
Magnesium atom yog cov qauv txheej txheem ntawm cov tshuaj magnesium. Txij li cov atomic tooj ntawm magnesium hlau yog 12, magnesium atom yuav tsum muaj 12 protons hauv nws cov nucleus. Lub atomic nucleus ntawm ib lub atom feem ntau muaj cov protons muaj cov hluav taws xob zoo thiab cov neutrons uas tsis muaj hluav taws xob (lawv yog cov khoom nruab nrab). magnesium atom yog ib hom tshuaj nruab nrab, yog li nws yuav tsum muaj 12 electrons orbiting nyob ib ncig ntawm lub atomic nucleus. Qhov no yog vim hais tias 12 tus nqi zoo los ntawm cov protons yuav tsum tau nruab nrab los ntawm 12 tus nqi tsis zoo (uas sawv cev rau 12 electrons) thiaj li tsim tau qhov nruab nrab nqi magnesium atom.
Lub teeb tsa hluav taws xob ntawm magnesium atom yog [Ne]3s 2 Txawm li cas los xij, muaj peb lub isotopes ruaj khov ntawm magnesium. Cov no yog Mg-24, Mg-25, thiab Mg-26. Yog li ntawd, txhua isotope muaj 12, 13 thiab 14 neutrons nyob rau hauv lawv cov atomic nuclei, feem. Txawm li cas los xij, tus naj npawb ntawm cov protons yuav tsum zoo ib yam rau txhua daim ntawv isotopic vim tias lwm yam, cov khoom siv tshuaj yuav yog qhov sib txawv (tus naj npawb ntawm cov protons txiav txim siab tus kheej ntawm cov tshuaj lom neeg).
Magnesium Ion yog dab tsi?
Magnesium ion yog cov qauv txheej txheem ntawm ionic magnesium compounds. Qhov ruaj khov tshaj plaws ionic daim ntawv ntawm magnesium yog Mg + 2 ion. Nws muaj oxidation xeev +2. Qhov no ion tsim los ntawm kev tshem tawm ntawm ob lub electrons los ntawm sab nraud lub atomic orbital. Txawm li cas los xij, tus naj npawb ntawm protons thiab neutrons yog tib yam li ua ntej. Ntxiv mus, tuaj yeem muaj Mg + 1 ion ib yam nkaus, tab sis nws tsis tshua pom muaj. Yog li ntawd, thaum peb hais magnesium ion, peb feem ntau yog xa mus rau Mg + 2 ion.
Magnesium ion tuaj yeem pom muaj nyob hauv ntau Mg-muaj ionic compounds. Nws muaj tus nqi zoo uas ua rau nws cov cation ntawm ntau yam yooj yim thiab complex compounds xws li organometallic compounds. Cov ion no yog ib qho yooj yim ion vim nws tsim cov tshuaj lom neeg yooj yim heev.
Qhov txawv ntawm Magnesium Atom thiab Magnesium Ion yog dab tsi?
Magnesium atom yog cov qauv txheej txheem ntawm cov tshuaj magnesium. Magnesium ion yog lub hauv paus txheej txheem ntawm ionic magnesium compounds. Qhov sib txawv tseem ceeb ntawm magnesium atom thiab magnesium ion yog magnesium atom muaj 12 electrons thiab nws yog ib hom tshuaj nruab nrab, hos magnesium ion muaj 10 electrons thiab nws yog ib hom tshuaj zoo.
Cov infographic hauv qab no teev qhov sib txawv ntawm magnesium atom thiab magnesium ion nyob rau hauv daim ntawv tabular rau ib sab kev sib piv.
Summary – Magnesium Atom vs Magnesium Ion
Magnesium yog ib qho tshuaj lom neeg uas peb tuaj yeem pom nyob rau hauv lub sijhawm ntawm cov ntsiab lus. Cov khoom no muaj 12 protons thiab electrons hauv ib lub atom. Qhov sib txawv tseem ceeb ntawm magnesium atom thiab magnesium ion yog magnesium atom muaj 12 electrons thiab nws yog ib hom tshuaj nruab nrab, hos magnesium ion muaj 10 electrons thiab nws yog ib hom tshuaj zoo.
