Metal hydrides yog cov hlau uas tau raug khi rau hydrogen los ua ib qho kev sib txuas tshiab. … Feem ntau, daim ntawv cog lus yog covalent nyob rau hauv cov xwm, tab sis ib co hydrides yog tsim los ntawm ionic bondsCov hydrogen muaj oxidation naj npawb ntawm -1. Cov hlau nqus cov pa roj, uas tsim cov hydride.
Puas yog hydrides ionic lossis covalent?
Cov tshuaj no tau muab faib ua peb yam tseem ceeb raws li qhov xwm ntawm lawv txoj kev sib raug zoo: Ionic hydrides, uas muaj cov cim tseem ceeb ionic bonding. Covalent hydrides, uas suav nrog cov hydrocarbons thiab ntau lwm cov tebchaw uas covalently khi rau hydrogen atoms.
Vim li cas hlau hydrides yog ionic?
Ionic Hydrides
Cov tebchaw no tsim ntawm hydrogen thiab cov hlau nquag tshaj plaws, tshwj xeeb tshaj yog nrog cov alkali thiab alkaline-lub ntiaj teb hlau ntawm pawg ib thiab ob lub ntsiab lus. Hauv pawg no, hydrogen ua raws li hydride ion (H-). Lawv bond nrog ntau electropositive hlau atoms
Dab tsi yog hydrides piav qhia ionic thiab metallic hydrides?
Ionic hydrides tsim thaum hydrogen reacts nrog electropositive s-block ntsiab; covalent hydrides tsim thaum atoms ntawm cov tshuaj muaj xws li electronegativity qhov tseem ceeb react nrog hydrogen whereas metallic hydrides tsim thaum hloov hlau react nrog hydrogen.
Ionic hydrides muab piv txwv yog dab tsi?
1) Ionic hydride: Thaum hydrogen tsim cov khoom sib xyaw nrog pawg IA, nws tsim cov ionic hydride. Piv txwv li – Lithium Hydride (LiH), Sodium Hydride (NaH), Potassium hydride (KH).
