(a) X and Y belong to the same period in the Periodic Table is a group I element while Y belongs to group VII. State which of the elements would
(i) be a good oxidizing agent
(ii) have the smaller atomic volume
(iii) have the higher ionization potential
(b) Explain your answer in (a)(i) above.
Explanation
(a) (i) Element Y
(ii) Element Y
(iii) Element Y
(b) The element Y is in group VII and so it has a smaller atomic volume than element X which is in group
I. This size of the atom is a measure of the atomic radius. The smaller the atom is, the more is the attractive force between the outermost electron and the nucleus and this is the reason why element Y will be a better acceptor of electron than X as oxidizing agent.
