Beryllium, atomic tooj 4, atomic hnyav 9.012182, yog lub lightest alkaline ntiaj teb hlau ntsiab
dawb.Beryl thiab emerald tau chemicalized los ntawm Fabkis chemist Walkerland hauv 1798
pom thaum tsom xam.Xyoo 1828 German chemist Willer thiab Fabkis chemist Bissy
Ntshiab beryllium yog tau los ntawm kev txo cov molten beryllium chloride nrog hlau poov tshuaj, feem.Nws lub npe Askiv yog Wei
Le npe.Cov ntsiab lus ntawm beryllium nyob rau hauv lub ntiaj teb crust yog 0.001%, thiab lub ntsiab mineral yog beryl.
, beryllium thiab chrysoberyl.Ntuj beryllium muaj peb isotopes: beryllium 7, beryllium 8,
Beryllium 10.
Beryllium yog hlau grey hlau;melting point 1283 ° C, boiling point 2970 ° C, ceev 1.85 g / cm³, beryllium ion radius 0.31 angstroms, ntau me dua lwm yam hlau.
Beryllium yog tshuaj lom neeg thiab tuaj yeem tsim cov txheej txheej oxide tiv thaiv, txawm tias
Beryllium kuj tseem ruaj khov hauv huab cua thaum tshav kub kub.Beryllium tuaj yeem cuam tshuam nrog dilute acid, thiab
Soluble nyob rau hauv muaj zog alkali, qhia amphoteric.Oxides thiab halides ntawm beryllium muaj qhov pom tseeb
Obviously covalent, beryllium tebchaw yog yooj yim decomposed nyob rau hauv dej, thiab beryllium kuj tuaj yeem tsim polymerization.
thiab covalent tebchaw nrog cov thermal stability tseem ceeb.
Hlau beryllium feem ntau yog siv los ua tus neeg nruab nrab neutron hauv cov reactors nuclear.Beryllium tooj liab alloy yog siv rau
Kev tsim cov cuab yeej tsis muaj teeb meem, xws li qhov tseem ceeb txav ntawm aero-engines,
Precision instruments, thiab lwm yam. Beryllium vim nws lub teeb yuag, siab elastic modulus thiab zoo thermal stability,
Nws tau dhau los ua ib lub dav hlau tsim nyog thiab cov khoom siv foob pob hluav taws.
