19. (i) What is the co-ordination number of Na+ inNaCl crystal ?

1.	19. (i) What is the co-ordination number of Na+ inNaCl crystal ?
Answer» Answer: Six The coordination number of sodium is 6. LIKEWISE, six sodium ions immediately surround each chloride ions, MAKING the coordination number of chloride also equal to 6. Because the FORMULA UNIT of sodium chloride displays a 1:1 ratio between the ions, the coordination numbers must be the same.
