An element X which occurs in the second ...

An element X which occurs in the second short period has an outer electronic structure `s^2p^1` What are the formula and acid -base character of its oxides ?

A

`XO_3`, basic

B

`X_2 O_3`, basic

C

`X_2, O_3`, acidic

D

`XO_2`, acidic

Text Solution

Verified by Experts

The correct Answer is:
C
[X] element with electronic configuration `s^2 p^1` can show +3 oxidation state
`X = + 3" " O = -2` hence `X_2 O_3`.
