Covalent Bond

Covalent Bond

The figure that show how every silicon atom takes position itself to their adjacent silicon atom and make a silicon crystal. With their four valence electron of silicon donates an electron with every of its four neighbors. For each atom creates an eight shared valence electrons and produced the chemical stability. This type of sharing outer electron produced a covalent bonds that holds the atom together. Each valence electron is equally attracted by its adjacent atom. The impurities that are found in intrinsic silicon crystal in figure its shows clearly. The covalent bounding of germanium is same because it has also four

Covalent bounding of Silicon is given in figure.
