There are in total 5 states in the Whole wide World. In a solid, particles are packed tightly together so they are unable to move about very much. Particles of a solid have very low kinetic energy. The electrons of each atom are in motion, so the atoms have a small vibration, but they are fixed in their position. Solids have a definite shape. They do not conform to the shape of the container in which they are placed.

Some mining was done from about 1886 to 1940, but was reportedly minor.
