Saline hydrides (tseem hu ua ionic hydrides lossis pseudohalides) yog cov khoom sib xyaw 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 yam. Hauv pab pawg no, hydrogen ua raws li hydride ion (H−).
YYog hydrides covalent lossis ionic?
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. Interstitial hydrides, uas tej zaum yuav piav tau hais tias muaj metallic bonding.
YYuav ua li cas hom ion yog hydride?
Saline, lossis ionic, hydrides yog txhais los ntawm muaj hydrogen raws li qhov tsis zoo ion (i.e., H−). Cov saline hydrides feem ntau suav hais tias yog hydrides ntawm alkali hlau thiab alkaline ntiaj teb hlau (yog tias muaj kev zam ntawm beryllium hydride, BeH2, thiab magnesium hydride, MgH 2).
YYuav ua li cas hydride yog ionic hydride?
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).
Puas yog ionic hydride daim ntawv?
Mainly group 1 and group 2 elements form ionic hydrides. Tam sim no, ntawm cov khoom sib txuas, $Ca{H}_{2}$, $Ba{H}_{2}$, $Sr{H}_{2}$, thiab $Be{H}_{2} $, lub hauv paus atoms yog Ca, Ba, Sr thiab Be. … Tab sis, txawm yog ib qho electropositive keeb beryllium cov ntaub ntawv thiab covalent daim ntawv cog lus nrog hydrogen es tsis tsim ib tug ionic hydride.
