Question 4

What is an emission spectra and what evidence does it provide for the Bohr model of the atom

Answer 4

The distribution of electromagnetic radiation released by a substance whose atoms have been excited by heat or radiation. Heating a substance excites its protons in which the proton will move to a different orbit changing its colour
