To determine the overall charge on the structure when a trivalent atom replaces a few silicon atoms in the three-dimensional network of silicon dioxide, we can follow these steps: ### Step-by-Step Solution 1. **Understanding the Structure of Silicon Dioxide (SiO₂)**: - Silicon (Si) is a tetravalent atom, meaning it has a valency of 4. In the three-dimensional network of SiO₂, each silicon atom is bonded to four oxygen atoms, and each oxygen atom is bonded to two silicon atoms. 2. **Replacing Silicon with a Trivalent Atom**: ...

Only those atoms which four covalent bonds produce a repetitive three dimesional structure using only covalent bonds., e.g. , diamond structure.The latter is based on a FCC lattice where lattice points are occupied by carbon atoms.Every atom in this structure is surrounded tetrahedrally by four others.Germanium, silicon and grey tin also crystallize in the same way as diamond. (Given : N_A=6xx10^(23) sin 54^@44'=0.8164 ) If edge length of the cube is 3.60Å , then radius of carbon atom is
