when electrons move from the fourth energy level to the second energy level , they emit visible light. why is the light emitted when an electron makes this move in a sodium atom is a different color than the light emitted by an electron moving from the fourth to the second level of a hydrogen atom ?

Hello @jasmine145 ,
Welcome to OpenStudy !

When electrons jump from higher energy level to lower energy level they need to free themselves from the extra energy. For this they emit energy in the form of electromagnetic waves. Now it's not neccessary that they emit electromagnetic waves in the range of visible light all the time. But the wavelength emmited while jumping from 4th to 2nd (Balmar series) lies in the visible light spectrum.

You certainly didn't noticed but you posted your chemistry question in the bilogy section. Next time check if u r in correct section.
