Raws li Mohs hardness scale, ib daim ntawv teev mos hlau muaj xws li txhuas, kub, nyiaj, tin, zinc, txhuas, thorium, tooj liab, tooj dag thiab tooj liab. Gallium kuj tseem yuav xav txog ib soft hlau , raws li nws melts ntawm 85.57 degrees Fahrenheit. Mercury yog a hlau uas yog kua ntawm chav tsev kub.

Tsis tas li ntawd, cov hlau twg yog mos tshaj plaws?

Cesium suav hais tias yog tus softest hlau , Lead tseem suav nrog cov softest hlau . Teb 3: Mercuryis kua (molten) ntawm chav tsev kub. Gallium, thaum khov (yog tias mos ) nyob rau hauv chav tsev kub, yog kua ntawm lub cev kub.

Tsis tas li ntawd, puas yog txhuas hlau mos? Ntshiab aluminium (99.996 feem pua) yog heev mos thiab qaug zog; kev lag luam aluminium (99 mus rau 99.6 feem pua ntshiab) nrog me me ntawm silicon thiab hlau yog tawv thiab muaj zog. Ductile thiab malleable heev, aluminium tuaj yeem kos rau hauv cov hlau los yog dov rau hauv cov ntawv ci nyias. Cov hlau tsuas yog kwv yees li ib feem peb li ntom li hlau lossis tooj liab.

Ntawm no, cov hlau mos thiab tawv yog dab tsi?

Hlau ions nrog lub siab tshaj plaws affinities rau nyuaj bases yog nyuaj acids, yog hlau ions nrog lub siab tshaj plaws affinity rau mos bases yog mos kua qaub.

Kub puas yog hlau mos?

Kub hu ua hnyav hlau vim nws qhov siab ceev, uas yog los ntawm qhov tseeb tias txhua tus ntawm nws cov atomsis hnyav heev. Piv txwv li, kub atoms slidepast ib leeg kuj yooj yim, uas ua rau cov metalsoft thiab maleable.
