Qhov sib txawv tseem ceeb ntawm Lithium thiab lwm yam alkali hlau yog tias lithium yog cov hlau alkali nkaus xwb uas tuaj yeem hnov mob nrog nitrogen thaum lwm cov alkali hlau tsis tuaj yeem cuam tshuam nrog nitrogen.
Alkali hlau yog pawg 1 cov ntsiab lus ntawm lub sijhawm ntawm cov ntsiab lus. Txawm li cas los xij, nws tsis suav nrog hydrogen vim nws muaj cov khoom tsis yog xim hlau. Yog li, cov khoom siv tshuaj uas peb tuaj yeem hu ua alkali hlau muaj xws li Lithium, Sodium, Potassium, Rubidium, Cesium thiab Francium. Txawm hais tias lithium yog ib tus tswv cuab ntawm pab pawg no, nws muaj qee qhov tshwj xeeb tshaj li lwm cov hlau alkali xws li muaj peev xwm ua rau cov pa nitrogen.
Lithium yog dab tsi?
Lithium yog cov hlau alkali muaj tus lej atomic 3 thiab cov cim tshuaj Li. Raws li qhov loj bang txoj kev xav ntawm kev tsim lub ntiaj teb, lithium nrog rau hydrogen thiab helium yog cov tshuaj tseem ceeb uas tsim nyob rau theem ntxov ntawm lub ntiaj teb tsim. Lub atomic qhov hnyav ntawm lub caij no yog 6.941, thiab lub teeb tsa hluav taws xob yog [Nws] 2s 1Ntxiv mus, nws yog nyob rau hauv s block vim nws yog nyob rau hauv pawg 1 ntawm lub sij hawm thiab lub sij hawm. melting thiab boiling cov ntsiab lus ntawm cov khoom no yog 180.50 ° C thiab 1330 ° C feem. Nws tshwm nyob rau hauv cov xim silvery-dawb, thiab yog tias peb hlawv cov hlau no, nws muab cov nplaim xim liab.
Daim duab 01: Lithium Hlau
Cov hlau no yog lub teeb thiab mos heev. Yog li peb tuaj yeem txiav nws yooj yim siv rab riam. Tsis tas li ntawd, nws tuaj yeem ntab rau hauv dej, ua rau muaj tshuaj lom neeg tawg. cov hlau no muaj qee yam khoom tshwj xeeb uas lwm cov hlau alkali tsis muaj. Piv txwv li, nws tsuas yog alkali hlau uas tuaj yeem hnov mob nrog cov roj nitrogen thiab nws tsim lithium nitride raws li cov tshuaj tiv thaiv no. Nws yog qhov tsawg tshaj plaws ntawm lwm cov tswv cuab ntawm pab pawg no. Ntxiv mus, nws muaj qhov tsawg kawg nkaus ntawm cov khoom hlau.
Dab tsi yog Alkali Metals?
Alkali hlau yog cov tshuaj lom neeg hauv pawg 1 ntawm cov lus ntu ntu ntawm cov ntsiab lus tshwj tsis yog hydrogen. Yog li, cov tswv cuab ntawm pawg no uas poob rau hauv pawg no yog Lithium, Sodium, Potassium, Rubidium, Cesium thiab Francium. Qhov laj thawj vim li cas peb thiaj li hu lawv ua cov hlau alkali yog tias lawv tsim cov tshuaj alkali.
Daim duab 02: Alkali hlau hauv xim liab
Thaum xav txog qhov kev teeb tsa hluav taws xob ntawm lawv, lawv muaj lawv cov hluav taws xob sab nraud hauv ib lub orbital; yog li ntawd lawv nyob rau hauv lub block ntawm lub periodic rooj. Cov tsiaj uas ruaj khov tshaj plaws uas lawv tsim yog monovalent cation.
Qhov txawv ntawm lithium thiab lwm yam Alkali hlau yog dab tsi?
Lithium yog cov hlau alkali uas muaj tus lej atomic 3 thiab cov cim tshuaj Li thaum cov hlau alkali yog cov tshuaj lom neeg hauv pawg 1 ntawm lub sijhawm ntawm cov ntsiab lus tshwj tsis yog hydrogen. Qhov sib txawv tseem ceeb ntawm Lithium thiab lwm yam alkali hlau yog tias lithium tsuas yog alkali hlau uas tuaj yeem hnov mob nrog nitrogen thaum lwm cov hlau alkali tsis tuaj yeem cuam tshuam nrog nitrogen. Ntxiv mus, lithium tsis tuaj yeem tsim anion thaum lwm cov hlau alkali tuaj yeem tsim anions.
Cov hauv qab no infographic tabulates qhov sib txawv ntawm Lithium thiab lwm yam alkali hlau raws li ib sab ntawm kev sib piv.
Summary – Lithium vs Lwm Alkali Metals
Lithium yog ib tus tswv cuab ntawm pawg alkali hlau. Qhov sib txawv tseem ceeb ntawm Lithium thiab lwm yam alkali hlau yog tias lithium yog cov hlau alkali nkaus xwb uas tuaj yeem hnov mob nrog nitrogen thaum lwm cov hlau alkali tsis tuaj yeem cuam tshuam nrog nitrogen.
