Beryllium, nambala ya atomiki 4, kulemera kwa atomiki 9.012182, ndiye chinthu chopepuka kwambiri cha zitsulo zamchere padziko lapansi.Zinapezeka mu 1798 ndi katswiri wa zamankhwala waku France Walkerland pakuwunika kwamankhwala a beryl ndi emarodi.Mu 1828, katswiri wa zamankhwala wa ku Germany Weiler ndi katswiri wa zamankhwala wa ku France Bixi anachepetsa beryllium chloride yosungunuka ndi chitsulo cha potaziyamu kuti apeze beryllium yoyera.Dzina lake la Chingerezi limatchedwa Weller.Zomwe zili mu beryllium pansi pa nthaka ndi 0.001%, ndipo mchere waukulu ndi beryl, beryllium ndi chrysoberyl.Natural beryllium ili ndi isotopu zitatu: beryllium-7, beryllium-8, ndi beryllium-10.

Beryllium ndi chitsulo chotuwa chachitsulo;malo osungunuka 1283 ° C, kuwira 2970 ° C, kachulukidwe 1.85 g/cm³, beryllium ion radius 0.31 angstroms, yaying'ono kwambiri kuposa zitsulo zina.

The mankhwala katundu beryllium yogwira ndipo akhoza kupanga wandiweyani pamwamba okusayidi zoteteza wosanjikiza.Ngakhale kutentha kofiira, beryllium imakhala yokhazikika mumlengalenga.Beryllium sangathe kuchitapo kanthu ndi asidi wochepetsetsa, komanso kupasuka mu alkali wamphamvu, kusonyeza amphoteric.Ma okosijeni ndi ma halides a beryllium ali ndi zinthu zodziwikiratu, zopangira za beryllium zimawola mosavuta m'madzi, ndipo beryllium imatha kupanganso ma polima ndi ma covalent omwe ali ndi kukhazikika kwamafuta.

Metal beryllium imagwiritsidwa ntchito makamaka ngati nyutroni woyang'anira mu zida zanyukiliya.Beryllium copper alloys amagwiritsidwa ntchito popanga zida zomwe sizimapanga zopsereza, monga mbali zazikulu zosuntha za injini za aero, zida zolondola, ndi zina. ndi kukhazikika kwamafuta abwino.Mankhwala a Beryllium ndi owopsa m'thupi la munthu ndipo ndi chimodzi mwazowopsa zamakampani.
