Question

which have larger bond lenght among N-3,O-2,F-​

Answer 1

Answer:-ve sign means more of electrons and +ve sign means lack of electrons.

Here N3- with atomic no. 7 has 7+3= 10 electrons

O2- witha tomic no. 8 has 8+2 = 10 electrons

F- with atomic no. 9 has 9+1= 10 electrons

hence the order is f-<o2-<n3-
