Q. The correct order of electronegativity of N , C, P and O is
Solution:
- Electronegativity , symbolized as ? , is the tendency of an atom to attract shared electrons (or electron density) to itself .
- An atom’s electronegativity is affected by both its atomic number and the distance at which its valence electrons reside from the charged nucleus .
- Metals show a lower value of electronegativity as compared to the non-metals .
- Fluorine is the most electronegative element on the periodic table .
- Cesium is the least electronegative element .
- The value of electronegativity increases across a period and the value of electronegativity decreases as we move down the group .
