SUMMARY
The coordination number (C.N.) of cations in relation to anions can be determined from the chemical formula of a compound, specifically by analyzing the crystal structure. In the case of grossular garnet (Ca3Al2Si3O12), the coordination numbers for Ca2+, Al3+, and Si4+ are influenced by the arrangement of these ions within the crystal lattice. Understanding the structure is essential for accurate determination, as it directly affects the spatial arrangement of the ions.
