In the given 15 group elements which element is the least electronegative?
Nitrogen
Arsenic
Phosphorus
Antimony
Antimony is the least electronegative among Group 15 elements due to its relatively large atomic size and low effective nuclear charge. Hence option 4 is the correct answer.
Option(1) Antimony is the least electronegative among Group 15 elements due to its relatively large atomic size and low effective nuclear charge. Hence option 1 is incorrect.
Option(2) Antimony is the least electronegative among Group 15 elements due to its relatively large atomic size and low effective nuclear charge. Hence option 2 is incorrect.
Option(3) Antimony is the least electronegative among Group 15 elements due to its relatively large atomic size and low effective nuclear charge. Hence option 3 is incorrect.
