boron family

Let us learn about boron family

Boron family exists in the earth's crust to the extent of only about ten ppm. The pure & original element is shiny & black. Boron is very hard & in extremely pure form is nearly as hard as diamond, but much too brittle for practical use. At high temperatures boron is a good conductor but at room temperature & below is an insulator. This behavior & many of its other properties earns it the classification of a metalloid. In order to the crystalline form of boron there is also an amorphous dark brown powder

Boron exhibit -3 oxidation state in borides example Mg₃B₂

No regular trend is noticed in the melting points of these elements in order to the structural changes in the elements. The M.P is high because it exists as large covalent polymer in solid & liquid states. The low melting point of gallium is because to its simple molecular structure.

Boiling point decrease frequently in boron family
