Classification Of Elements And Periodicity In Properties Ques 307
Question: When an isolated gaseous cation $ {{X}^{+}}(g) $ is converted into $ {{X}^{-}}(g) $ anion, the amount of energy released is 16.8 eV. Calculate the electro negativity value of the atom X on Pauling’s scale.
Options:
A) 1
B) 2
C) 4
D) 3
Show Answer
Answer:
Correct Answer: D
Solution:
[d] $ {{X}^{+}}(g)\xrightarrow[{}]{{}}{{X}^{-}}(g); $ Energy $ =IE+IA=16.8,eV $ $ EN_{pauling}=\frac{IA+EA}{5.6}=\frac{16.8}{5.6}=3 $
