1.) If the spacing between two electronic energy levels in atom A is larger than in atom B, then the wavelength of the light emitted by atom B will be longer.

Question

2.) If the spacing between two electronic energy levels in atom A is smaller than in atom B, then fewer photons will be emitted by atom B.
Would these statements be true or false? Also, can someone explain why please, thanks!

Answer 1

larger energy difference means photon of higher energy which is higher frequency which is SHORTER wavelength
wavelength = c T = c/f
and energy = h f

2. is just nonsense. The energy of individual photons is the energy change between levels. It has noting to do with number of photons.

Answer 2

HEY - looking at all your questions, you better read the chapter or Google atomic spectra and photons
