Beryllium, numero ya atome 4, uburemere bwa atome 9.012182, nikintu cyoroshye cya alkaline yisi yicyuma
cyera.Beryl na zeru byatewe imiti na chimiste w’abafaransa Walkerland mu 1798
byabonetse mugihe cyo gusesengura.Mu 1828, umuhanga mu by'imiti w’umudage Willer na Bissy w’umufaransa
Beriliyumu nziza iboneka mugabanya berilium ya chloride yashongeshejwe hamwe na potasiyumu ya metani.Izina ryicyongereza ni Wei
Le.Ibiri muri beryllium mubutaka bwisi ni 0.001%, naho minerval nyamukuru ni beryl
, beryllium na chrysoberyl.Beriliyumu isanzwe ifite isotopi eshatu: beryllium 7, beryllium 8,
Beryllium 10.
Beryllium ni icyuma kijimye;gushonga 1283 ° C, ingingo itetse 2970 ° C, ubucucike bwa 1,85 g / cm³, beryllium ion radius 0.31 angstroms, ntoya cyane kuruta ibindi byuma.
Beryllium ikora muburyo bwa chimique kandi irashobora gukora igipimo cyinshi cya oxyde irinda, nubwo niyo
Beryllium nayo ihagaze neza mu kirere ku bushyuhe butukura.Beryllium irashobora kwitwara hamwe na acide ya dilute, nayo
Gukemura muri alkali ikomeye, yerekana amphoteric.Oxide na halide ya beryllium biragaragara
Biragaragara ko covalent, ibibyimba bya beryllium byangirika byoroshye mumazi, kandi beryllium nayo ishobora gukora polymerisation
hamwe na covalent compound hamwe nubushyuhe bukomeye bwumuriro.
Ibyuma bya beryllium bikoreshwa cyane nka moderi ya neutron mumashanyarazi.Beryllium y'umuringa ukoreshwa kuri
Gukora ibikoresho bidacana, nkibice byimuka bya moteri ya aero-moteri,
Ibikoresho bya precision, nibindi Beryllium kubera uburemere bwayo bworoshye, modulus ya elastike yo hejuru hamwe nubushyuhe bwiza bwumuriro,
Yabaye indege ikomeye nibikoresho bya misile.
