Answer all the following questions 1.Calcium (Ca), chlorine (Cl2) and calcium chloride (MgF2) have different types ofbonding and different properties.(a)Calcium has metallic bonding.(i)Draw a diagram to show what is meant by metallic bonding. Label thediagram.Use your diagram to explain how calcium conducts electricity. Ans. Metallic bonding takes place for the formation of organized lattice structures. From the above illustration, it can be clearly demonstrated that calcium is a metal of atomic number 20, it has extra 2 valence electrons in the outermost cellthat are mobile and are free to move in the lattice. It has a non-directional bond and is formed due to the inter-facial attraction of these Ca free electrons with the kernels to bind and form a bond called as metallic bond. Henceforth, these mobile electrons are the promoter of electrical conductivity. In presence of potential difference on the metal sheet, the free electrons move towards positiveelectrode and later it gets replaced from negative electrode on simultaneous conditions.
