B - Boron - METALLOIDS

Boron, of symbol B, atomic mass 10.8 and atomic number 5, is the only element in its group which is not a metal. Boron in its solid black form is brittle and very hard. In its form The amorphous form boron is a brown-black powder. There is no simple body in the native state, it is found in the form of borax. It constitutes about 0.001% of the earth's crust. Boron is used in metallurgy, and in various detergent products, soaps, disinfectants ...
