Problem- Which of the following is/are correct postulates of Bohr's theory of the hydrogen atom? Provide written rationale.
1) The energy of an electron in an atom is quantized (i.e. only specific energy values are possible).
2) The principal quantum number (n), specifies each unique energy level.
3) An electron transition from a lower energy level to a higher energy level results in an emission of a photon of light.
Specifically, why aren't 3. True here, if that is the case. Several points will be awarded, please tap in to your knowledge as well as lay out some logic in your responses.
Please provide the answer of the given question on urgent basis
