I-Beryllium, inombolo ye-athomu yesi-4, ubunzima be-athomu 9.012182, yeyona nto ikhaphukhaphu yesinyithi yomhlaba.Ifunyenwe kwi-1798 yi-chemist yaseFransi i-Walkerland ngexesha lokuhlalutya kweekhemikhali ze-beryl kunye ne-emerald.Ngomnyaka we-1828, i-chemist yaseJamani u-Weiler kunye ne-chemist yaseFransi u-Bixi banciphisa i-beryllium chloride etyhidiweyo kunye nesinyithi se-potassium ukufumana i-beryllium ecocekileyo.Igama layo lesiNgesi lithiywe ngoWeller.Umxholo we-beryllium kwi-crust yomhlaba ngu-0.001%, kwaye iiminerali eziphambili ziyi-beryl, i-beryllium kunye ne-chrysoberyl.I-beryllium yendalo ine-isotopes ezintathu: i-beryllium-7, i-beryllium-8, kunye ne-beryllium-10.

Iberyllium yintsimbi engwevu;indawo yokunyibilika 1283°C, iqondo lokubila 2970°C, ingxinano 1.85 g/cm³, beryllium ion radius 0.31 angstroms, incinci kakhulu kunezinye iintsimbi.

Iimpawu zeekhemikhali ze-beryllium ziyasebenza kwaye zinokwenza i-dense surface oxide layer protective.Nakubushushu obubomvu, i-beryllium izinzile emoyeni.I-Berryllium ayinakusabela kuphela nge-asidi edibeneyo, kodwa iphinde ichithe kwi-alkali enamandla, ibonisa i-amphoteric.I-oxides kunye ne-halides ye-beryllium ineempawu ezicacileyo, iikhompawundi ze-beryllium zichithwa ngokulula emanzini, kwaye i-beryllium inokwenza iipolymers kunye ne-covalent compounds kunye nokuzinza okucacileyo kwe-thermal.

I-Metal beryllium isetyenziswa ikakhulu njengemodareyitha ye-neutron kwiireactors zenyukliya.I-Beryllium i-alloys yobhedu isetyenziselwa ukwenza izixhobo ezingavelisi iintlantsi, njengeendawo eziphambili ezihambayo ze-aero-injini, izixhobo ezichanekileyo, njl njl. I-Berryllium ibe yinto ekhangayo yesakhiwo seenqwelomoya kunye nemijukujelwa ngenxa yobunzima bayo obulula, imodyuli ephezulu yokuqina. kunye nokuzinza okuhle kwe-thermal.Iikhompawundi zeBeryllium ziyityhefu emzimbeni womntu kwaye yenye yeengozi ezinkulu zemizi-mveliso.
