Answer :
The correct relationship between the three values will be the value for nitrogen is greater than that of P because N is smaller, but less than that of O because N has a smaller effective nuclear charge.
Electronegativity is the chemical property which describes the tendency of an atom or a functional group which attract electrons toward itself. The electronegativity of an atom will be affected by both its atomic number as well as the distance that its valence electrons reside from the charged nuclei.
The electronegativity of phosphorus will be 2.19 is much less electronegativity than to the nitrogen. The electronegativity of nitrogen will be 3.04. 4. Phosphorus will expand its valence shell to hold more than eight electrons, but nitrogen cannot.
