Magnesium yog ib tug greyish-dawb, ncaj hlau tawv. Magnesium yog qhov thib yim tshaj plaws keeb nyob rau hauv lub ntiaj teb lub crust txawm tsis pom nyob rau hauv nws lub elemental daim ntawv. Nws yog ib Pab pawg 2 keeb ( Pab pawg IIA nyob rau hauv cov laus labeling schemes). Pab pawg 2 lub ntsiab yog hu ua alkaline ntiaj teb hlau.
Kuj nug, lub sijhawm twg yog MG?
Qhov tseeb lub thawv
| Pab pawg | 2 | 650 ° C, 1202 ° F, 923 K |
|---|---|---|
| Lub sijhawm | 3 | 1090 ° C, 1994 ° F, 1363 K |
| Thaiv | s | 1.74 |
| Atomic naj npawb | 12 | 24.305 |
| Lub xeev ntawm 20 ° C | Khoom | 24Mg |
Qhov thib ob, mg yog hlau lossis nonmetal? Cov tub ntxhais kawm pawg tau faib magnesium , zinc , hlau thiab tin li hlau ; sulfur ua nonmetal thiab silicon thiab carbon li metalloids. Cov pa roj carbon ua hluav taws xob thiab tsis muaj cov yam ntxwv luster.
Yog li ntawd, koj tuaj yeem piav qhia qhov chaw ntawm magnesium nyob rau lub sijhawm li cas?
Raws li peb tsiv hla kab thib peb ntawm tus daim ntawv qhia hnub , peb nrhiav magnesium ( Mg ) nyob rau hauv lub thib ob txoj hauj lwm . Nyob nyob rau hauv kab thib ob ntawm lub daim ntawv qhia hnub , magnesium yog nyob rau hauv tsev neeg ntawm alkaline ntiaj teb hlau nrog calcium (Ca) thiab beryllium (Be). Thaum purified, magnesium yog ib lub teeb heev thiab silvery hlau.
Leej twg pom magnesium?

Dab tsi yog lub ntsiab lus 11 ntawm lub rooj zaum?
Sodium yog lub ntsiab lus uas yog atomic naj npawb 11 ntawm lub sijhawm teem sijhawm
Cov pab pawg nyob qhov twg ntawm lub rooj zaum?
Nyob rau hauv chemistry, ib pab pawg (tseem hu ua tsev neeg) yog ib kem ntawm cov ntsiab lus nyob rau hauv lub sij hawm lub sij hawm ntawm cov tshuaj. Muaj 18 pawg lej nyob rau hauv daim ntawv teev sijhawm; cov kab f-block (nruab nrab ntawm pawg 3 thiab 4) tsis suav nrog
Dab tsi yog thawj lub ntsiab lus ntawm lub rooj zaum?
Hydrogen yog thawj lub hauv paus ntawm lub rooj sib tham, nrog qhov nruab nrab atomic loj ntawm 1.00794
Tsab ntawv C yog dab tsi rau ntawm lub rooj zaum?
Lub cim tshuaj yog qhov luv ntawm lub npe ntawm lub caij. Cov cim tshuaj ntawm tag nrho cov ntsiab lus tau teev nyob rau hauv daim ntawv teev sijhawm. Lawv kuj tau siv thaum sau cov tshuaj sib npaug. Piv txwv li: C + O2 → CO2. Ntawm no C sawv rau carbon thiab O sawv rau oxygen
Cov pab pawg twg yog europium nyob rau ntawm lub rooj zaum?
