Arrange the following elements in increasing order of electronegativity : 
N, O, F, C, Si
Choose the correct answer from the options given below:

Professor PC Thomas Classes · Answer

(a) : The electronegativity value of elements increases along a period from left to right and decreases down a group. This is because as we move along the period from left to right nuclear charge increases and atomic radius decreases whereas, when we move down the group atomic radius as well as screening effect increases. Thus the order of electronegativity is \ $ \mathrm{Si}<\mathrm{C}<\mathrm{N}<\mathrm{O}<\mathrm{F} $
