Lithium Properties

Lithium muaj ib melting point ntawm 180.54 C, kub taw tes ntawm 1342 C, lub ntiajteb txawj nqus ntawm 0.534 (20 C), thiab valence ntawm 1. Nws yog lub lightest ntawm cov hlau, nrog ib tug ceev kwv yees li ib nrab ntawm cov dej. Nyob rau hauv cov xwm txheej zoo tib yam, lithium yog qhov tsawg kawg nkaus ntawm cov khoom siv.

Yog li ntawd, lub cev thiab tshuaj lom neeg ntawm lithium yog dab tsi?

Lithium yog ib tug heev mos, silvery hlau. Nws muaj qhov melting point ntawm 180.54 ° C (356.97 ° F) thiab qhov kub ntawm 1, 335 ° C (2, 435 ° F). Nws ceev yog 0.534 g ib cubic centimeter. Los ntawm kev sib piv, lub ceev dej yog 1.000 grams ib cubic centimeter.

Ib yam li ntawd, lithium puas yog ib qho khoom siv? Lithium (los ntawm Greek: λίθος, romanized: lithos, lit. 'stone') yog ib qho tshuaj keeb nrog lub cim Li thiab atomic naj npawb 3. Nws yog ib tug mos, silvery-dawb alkali hlau. Nyob rau hauv cov xwm txheej txheem, nws yog cov hlau lightest thiab lub lightest khoom keeb.

Ntawm no, peb lithium zog yog dab tsi?
