Beryllium hydride (BeH2) is beryllium hydride, also known as polyberyllium, generally a white solid, heated to 240 ° C can put higher heat, decomposition into beryllium and hydrogen, resulting in large gas volume, commonly used as fuel for solid rocket engines.

Hydrogenated (BeH2) is a locked compound, generally a self-colored solid, chemical reagents heated to 240C can put higher heat, decomposed into plating and hydrogen, resulting in a large volume of gas, commonly used as a solid rocket engine fuel. Large pool leakage: Cover with plastic sheet and cloth. Can cause skin burns. It can cause perforation of the royal septum. Emergency response staff are advised to wear self-contained positive pressure breathing apparatus and protective clothing. Therefore, in the BE-H-BE bridge bond, there are naturally "banana-shaped" three central two-electron bonds. Isolate the contaminated area of leakage and restrict access. Stop the fire source. Do not contact spills directly.

Because the Be atom has only two valence electrons, there are not enough electrons in the hydrogenated compound to form a normal electron pair bond (that is, two electrons are shared between two atoms), and the hydrogenated compound is electron-deficient. Small amount of leakage: Avoid dust, use non-sparking tools collected in dry, clean, covered containers, transfer to a safe place. This is a cluster compound.
