"element towards the right of every period are non-metals (a) comment upon the gradation of tendency of gain electrons as we move from left to right in a period . justify the answer with reason (b) out of N and F, which atom do you think will be more electronegative and why ?

F is more electronegative because electronegativity increases across a period

here what is N ,F

a) tendency of gaining electrons as we move from left to right increases.
b) F (fluorine) will be more electronegative as it's atomic no. is 9 so the configuration would be 2,7 so it is easy to gain 1 electron as compared to nitrogen coz its atomic no. is 7 n configuration is 2,5 n it needs to gain 3 more electrons to become stable. so from this, fluorine will gain 1 electron more easily
b) F (fluorine) will be more electronegative as it's atomic no. is 9 so the configuration would be 2,7 so it is easy to gain 1 electron as compared to nitrogen coz its atomic no. is 7 n configuration is 2,5 n it needs to gain 3 more electrons to become stable. so from this, fluorine will gain 1 electron more easily
am sorry it is wrong answer
can u just explain how?
tendency to gain electrons increases as the nuclear charge increases and atomic radius decreases on moving from left to right in a period
i think b is right answer but a not right answer
