Due to the interatomic Si-O bonds' substantial covalent character and directionality, which restricts the efficiency of atom packing, silicate materials have relatively low densities.
By sharing electrons among nearby atoms, covalent bonds produce a stable electron configuration. At least one electron from each atom will be shared by two atoms that are covalently connected. A 3D structure is created. The bonds between atoms are very directional because electrons are shared between them. Because of this directionality, atomic packing is less dense and results in low density.
The second most plentiful element on earth, silicon, is a crucial component of the mineral world. Due to its solid tetrahedral structure, it is very adaptable and used in a variety of ways in our daily lives.
