Text Solution

Verified by Experts

`""_(12)Mg=2,8,2 " "therefore` Lewis symbol = Mg.
`""_(11) N_(a) = 2,8,1 " "therefore` Lewis symbol = Na
`""_(5)B = 2,3 " "therefore` Lewis symbol `= *overset(*)(B*)`
`""_(8)O = 2,6 ""therefore` Lewis symbol `= : overset(* *)B:`
`""_(7)N = 2,5 " "therefore` Lewis symbol `= : underset(*)overset(*)N*`
`""_(35)Br = 2,8, 18, 7 " "therefore` Lewis symbol `= :underset(* *)overset(* *)Br`
