It has a characteristic green flame color, and its tetrahydride salt, often considered a good hydrogen storage medium for fuel cells, is a common organic reducing agent, although weaker than lithium aluminum hydride. The Davis-Besse nuclear power plant in Ohio was shut down for several months as a result of corrosion by this element's most common acid, commonly used as an emergency neutron moderator for nuclear reactors, as well as a pesticide. It forms electron deficient compounds and its covalent trihydride is a canonical Lewis acid. Mostly found in Turkey and the United States, for 10 points name this element with atomic number 5 and symbol B.
