Solution

₆C, ₃Li, ₉F,₇N, ₈O
Electronic configuration of the following elements is:
₆C = 2,4
₃Li = 2,1
₉F = 2,7
₇N = 2,5
₈O = 2,6
₉F has the highest nonmetallic character because non-metallic character of an elements increases as we move from left to right in a period of the periodic table. This happens as the tendency of an atom to gain electrons increases due to increase in nuclear charge, the valence electrons are pulled in strongly by the nucleus and it becomes easier for an atom to gain electrons.
