Determining the composition of stars is one way that light emission has been used to determine the chemical composition of an object. light emission is still used today by researchers. it is harnessed in instrumentation such as flame atomic absorption spectroscopy. provide an explanation of how this instrument works as if you are describing it to your non-science roommate. also, provide at least two uses of such an instrument.

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.
