Question

An element X which occurs in the first short period has an outer electronic structure s²p¹. What are the formula and acid-base character of its oxides?

easy

Solution

Correct option is

X₂O₃, amphoteric

The outer electronic configuration = s²p¹

Thus, valency = 2 + 1 = 3

Therefore, the formula of the oxide is X₂O₃.

Since, it is an oxide of III group element, its nature is amphoteric.
