Consider the following values of I.E.(eV) for elements W and X:
`{:("Element",I.E_(1),I.E_(2),I.E_(3),I.E_(4)),(W,10.5,15.5,24.9,79.8),(X,8,14.8,78.9,105.8):}`
Other two element Y and Z hav outer electronic configuration `ns^(2)np^(4) and ns^(2)np^(5)` respectively. then according to given information which of the following compound(s) is/are not possible?

A

`W_2Y_3`

B

`X_2Y_3`

C

`WZ_2`

D

`XZ_2`

Text Solution

Verified by Experts

The correct Answer is:
B, C
W show oxidation state and X show oxidation state.
`Y = ns^(2) np^(4)` Y show - 2 oxidation state , `Z = ns^2 np^5` Z show - 1 oxidation state t
The compound that can be formed are :
(A) `W^(+3) + Y^(2-) = W_2Y_3 (B) x^(+2) + Y^(-2) = XY (C ) W^(+3) + Z^(-1) = WZ_3 (D) X^(+2) + Z^(-1) = XZ_2`
