Coordination number of the central atom is basically the number of atoms surrounding it. What is the coordination number for Na+in NaCl? The rutile crystal is shown below. Cadmium chloride is used in electroplating, printing, photocopying, dyeing, mirrors, vacuum tubes, lubricants, analytical chemistry and as a chemical intermediate to produce cadmium containing pigments and stabilizers. The chemical similarity and mild toxic nature of caesium salts does not provide much impetus to work with these compounds compared to their potassium analogues. Also as the ratio of C sCl is also as that of sodium hence we find that the coordination number remains as 8 in this case. Each unit cell has one cesium ion and one chloride ion. Hightlight the Cs's. This colorless solid is an important source of caesium ions in a variety of applications. Something like table salt (NaCl) is a compound because it is made from more than one kind of element (sodium and chlorine), but it is not a molecule because the bond that holds NaCl together is an ionic bond.
