37. The melting points and boiling points of some ionic compounds are given below: Compound NaCl LiCl CaCl CaO MgCh Melting Point (K) 1074 887 1045 2850 981 Boiling Point (K) 1686 1600 1900 3120 1685 These compounds are termed ionic because they are formed by the transfer of electrons from a metal to a non-metal. The electron transfer in such compounds is controlled by the electronic configuration of the elements involved. Every element tends to attain a completely filled valence shell of its nearest noble gas or a stable octet. (1) Show the electron transfer in the formation of magnesium chloride. (ii) List two properties of ionic compounds other than their high melting and boiling points. 1
