Consider a franck-hertz experiment with the following results. what would you expect to get for the highest wavelength spectral line for a gas of the same atoms? (this would be a way to test for consistency, to see if you are correctly interpreting the results in terms of atomic energy levels.) also, why would the current keep changing at multiples of the same value?

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.

the answers are

c and c
