An electron in a hydrogen atom moves from level 3 to level 1. in a second hydrogen atom, an electron drops from level 2 to level 1. which statement describes the most likely result?
the first atom emits light with more energy.
the second atom emits light with more energy.
the first and second atoms absorb energy without emitting light.
the first and second atoms emit light with the same amount of energy.

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.
