Question

Elements produce their spectrum when their electrons _____. are in the ground state move away from the ground state move toward the ground state all of the above

Answer 1

Option C, move toward the ground state

Step-by-step explanation:

When electron of an element move from a region of ground state to a region of high energy, it absorbs certain amount of energy. Now, when this electron starts moving from its excited stage to its ground stage it emits energy in the form of eigen states that vibrates with certain frequency just like the vibration of violin.

A spectrum is a distributed set of frequency and wavelength which corresponds to these eigen states

Hence otpion C is correct

Answer 2

The best answer to the question that is being presented above would be 'move toward the ground state'. Elements produce their spectrum when their electrons move toward the ground state. All the other choices do not fit the blank space provided.
