WebSep 27, 2024 · Since each type of atom in the NaCl structure forms a face-centered cubic lattice, there are four Na and four Cl atoms per NaCl unit cell. It is because of this ratio that NaCl has a 1:1 stoichiometry. The shaded green and gray bipyramidal structures in the NaCl lattice show that the Na + ions are coordinated to six Cl-ions, and vice versa. The ... green line cafe philly
