M is a metal above hydrogen in the activity series and its oxide has the formula M2O. This oxide when dissolved in water forms,the corresponding hydroxide which is a good conductor of electricity. In the above context answer the following: (i) What kind of combination exists between M and O ? (ii) How many electrons are there in the outermost shell of M ? (iii) Name the group to which M belongs. (iv) State the reaction taking place at the cathode. (v) Name the product at the anode.

Answer»

(i) Electrovalent bond exists between M and O. 

(ii) One electron is there in the outermost shell. 

(iii) M belongs to First group. 

(iv) M+ + e- -----> M (at cathode). 

(v) Oxygen gas is liberated at anode.
