(i) By the transfer of electrons, illustrate the formation of bond in magnesium chloride and identify the ions present in this compound.(ii) Ionic compounds are solids. Give reasons.(iii) With the help of a labeled diagram show the experimental setup of action of steam on a metal.
(i) Magnesium has Atomic Number = 12. Its electronic configuration is 2,8,2.
Chlorine has Atomic Number = 17. Its electronic configuration is 2,8,7.
The electron-dot structures of magnesium and chloride are given below:
Magnesium Chloride is formed by the transfer of 2 electrons from the outer shell of the magnesium atom to two chlorine atoms.
Hence, the ions present in the compound are (magnesium) Mg2+ and 2Cl- (chloride).
(ii) Ionic compounds are solid because In ionic compounds, very strong forces of attraction exist between positive and negative ions and forms a crystal structure.
(iii) The experimental set up of action of steam on a metal (magnesium) is shown below-
