Question

ON GOING DOWN IN A GROUP OF PERIODIC TABLE THERE IS NO CHANGE IN NATIRE OF OXIDE EXPLAIN WHY?​

Answer 1

because the valency remains the same

so the number of valence electrons also be the same

thus the formula of oxides is not affected

Answer 2

While moving down the group, the metallic character of elements increases. Metals form basic oxides.

When its an element of group 13 - 18, it has a tendency to have more of non metallic character ( since, metallic character decreases left to right across a period). Those elements form acidic oxides (non metals).

Therefore, on going down a group of periodic table, there is no change in nature of oxide of elements.
