The coordination number of sodium is 6. Portugal Weather Forecast October, You are correct. Coordination Numbers Examples: Example 1: Consider a methane molecule whose chemical formula is CH 4. 3. Because the formula unit of sodium chloride displays a 1:1 ratio between the ions, the coordination numbers must be the same. In almost all cases, oxygen atoms have oxidation numbers of -2. Draw and explain the unit cell of sodium chloride (NaCl) crystal determine effective number of NaCl molecule per unit cell and co-ordination number. The accepted explanation is that the ionic radii of cesium and chloride are very similar. Coordination Number refers to the number of atoms(or molecules or ions) attached to the central metal atom. Closed Packed Structures. The term was originally defined in 1893 by Swiss chemist Alfred Werner (1866–1919). Coordination Number.
