Brief description
 


Uses of Meitnerium
 

Arsenic is used as a doping agent in solid-state devices. Gallium arsenide is used in lasers which convert electricity into coherent light. Arsenic is used pyrotechny, hardening and improving the sphericity of shot, and in bronzing. Arsenic compounds are used as insecticides and in other poisons.
