Question

An element X which occurs in the second short period has an outer electronic structure s 2 p 1 . What are the formula and acid-base character of its oxides?, XO 3 , basic, X 2 O 3 , basic, X 2 O 3 , amphoteric, XO 2 , acidic

MARKS App · Accepted Answer

The outer electronic configuration = s 2 p 1 Thus, valency = 2 + 1 = 3 Therefore, the formula of the oxide is X 2 O 3 X is A l 2 O 3 , its nature is amphoteric
