Sodium oxide is an ionic compound made up of sodium and oxygen atoms. Sodium has one valance electron, and oxygen has six balance electrons. which is the ratio of sodium to oxygen atoms in sodium oxide? a. 1 : 2
b. 1 : 6
c. 2 : 1
d. 6 : 1

your answer is c) plasma

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
