Write Lewis dot symbols for atoms of the following elements: Mg, Na, B

1.	Write Lewis dot symbols for atoms of the following elements: Mg, Na, B, O, N, Br.
Answer» Solution :`""_(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`
