Question

M is a metal above hydrogen in the activity series and it's 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 :
1. what kind of combination exists between M and O?
2.how many electrons are there in the outermost shell of M ?
3. name the group to which m belongs ?
4. state the reaction taking place at the cathode.
5. name the product at the anode.

Answer 1

1)combination reaction

2)one

3)first group

4)

Answer 2

combination reaction
second -->it have 1 valence electron
third-->metal'm'belong to first group
fifth-->at anode there is anode mud only
