Gallium immediately converts the electricity into light. Another interesting thing is that Medical centers use gallium for the thermometers because Gallium is not toxic. One more thing to know about this important element is that it is obtained by electrolysis. Some more interesting facts about Gallium is that it gets used in Neutrino Observatory in Italy where they use it to study solar neutrinos. It is also used in the production of Lasers. Gallium is non-toxic
