3.23 How would you react to the statement that the electronegativity of N on Pauling scale is 3.0 in all the nitrogen compounds?

Electronegativity of an element is a variable property. It is different in different

compounds. Hence, the statement which says that the electronegativity of N on Pauling

scale is 3.0 in all nitrogen compounds is incorrect. The electronegativity of N is different in NH $_{3}$ and NO $_{2}$ .
