There is said to be about 0.0015% of gallium found in the Earth's crust with no known concentrated supplies of it
Gallium was discovered by Paul Emile Lecoq de Boisbaudran in 1875.
Gallium nitrite (Ga(NO2)3) is a compound formed by the elements gallium and nitrite ions. It is a nitrite salt of gallium, where gallium has a +3 oxidation state. Gallium nitrite is a crystalline solid that is not commonly found in nature.
You will not be able to find gallium around the house. Gallium, element number 31, does not occur in free form in nature. Gallium compounds can be found around the house in various electronics, such as microwave ovens and semiconductors, where it is either present as a gallium salt or an alloy.
It has coal
no
Gallium is often found as a trace element in diaspore, sphalerite, germanite, bauxite, and coal.
Gallium is not found as a rock, it is a metallic element which is found as a trace element in coal, bauxite, and some other rock minerals. In its pure form gallium is liquid near room temperature and is unusual in that it expands on solidifying.
Calculators do not typically contain gallium as a primary component. Gallium is a rare metal that is used in some electronic and semiconductor applications due to its unique properties, but it is not commonly found in calculators.
Gallium is not found free in nature, and it is present in only ppm (parts per million) quantities in minerals. For that reason, we recover gallium (III) salt as a byproduct of bauxite (a chief ore of aluminum) and sphalerite (a primary ore of zinc) processing. In either case, gallium chloride (GaCl3) is the salt we generally extract. Recovery of gallium from other sources is negligible.

Gallium is a metal. It belongs to group 13
