Question -
Answer -
Mg: There are two valence electrons in Mg atom. Hence, the Lewis dot symbol for Mg is:┬а┬а
Na: There is only one valence electron in an atom of sodium. Hence, the Lewis dot structure is:┬а
┬аB: There are 3 valence electrons in Boron atom. Hence, the Lewis dot structure is:┬а┬а
O: There are six valence electrons in an atom of oxygen. Hence, the Lewis dot structure is:┬а┬а
N: There are five valence electrons in an atom of nitrogen. Hence, the Lewis dot structure is:┬а┬а
Br: There are seven valence electrons in bromine. Hence, the Lewis dot structure is:┬а┬а
