Lithium beryllium
WebLithium is a chemical element with atomic number 3 which means there are 3 protons and 3 electrons in the atomic structure. The chemical symbol for Lithium is Li.. It is a soft, silvery-white alkali metal. Under standard conditions, it is the lightest metal and the lightest solid element. Like all alkali metals, lithium is highly reactive and flammable, and is stored in … The low atomic weight of lithium, beryllium and to a lesser extent fluorine make FLiBe an effective neutron moderator. As natural lithium contains ~7.5% lithium-6, which tends to absorb neutrons producing alpha particles and tritium, nearly pure lithium-7 is used to give the FLiBe a small neutron absorption cross section; e.g. the MSRE secondary coolant was 99.993% lithium-7 FLiBe. When Li-7 does absorb a neutron, it nigh-instantaneously decays via successive beta- and then alpha d…

They show the highest reversible hydrogen capacity (more than 8 wt.%) of all known metal hydrides. Measurements of equilibrium pressures of the Li–Be hydrides indicate that these materials can be used at temperatures down to 150°C.
