Question

"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 ?

Answer 1

F is more electronegative because electronegativity increases across a period

Answer 2

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
