Answer 3

Ok look consider the EN difference of the compounds being observed. F and Cu have a very large EN difference therefore they exhibit ionic bonding. Li and Br have a large EN difference and also exhibit ionic bonding. N and H have a small enough difference in EN to be considered to exhibit covalent bonding. O and Mg have large EN difference and therefore exhibit ionic bonding. so the answer would be N And H because the difference is so small

Thanks Shaima!
