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

(N/A) The electronegativity of an element is not a fixed value; it is a variable property that depends on the oxidation state and the chemical environment of the atom in a molecule.
Therefore,the statement that the electronegativity of $N$ on the Pauling scale is $3.0$ in all nitrogen compounds is incorrect.
For example,the electronegativity of $N$ varies depending on its hybridization and the nature of the atoms bonded to it,such as in $NH_3$ versus $NO_2$.
