Question:

1) For a hydrogen-like atom, classify these electron transitions by whether they result in the absorption or emission of light.

  • A) n = 1 to n = 3
  • B) n = 3 to n = 5
  • C) n = 2 to n = 1
  • D) n = 3 to n = 2

2) Ignoring sing, which transition is associated with the greatest energy change?

  • A) n = 2 to n = 1
  • B) n = 3 to n = 2
  • C) n = 3 to n = 5
  • D) n = 1 to n = 3

Bohr's Atomic Model:

Rutherford's Model failed to explain the stability of an atom since the electrons around the nucleus must fall into the nucleus. Thus, Bohr introduced his theory which stated that the electrons are present around the nucleus in fixed energy shells, numbered as 1, 2, 3, etc.

When an electronic transition occurs, it occurs with the energy absorbed or emitted equal to the difference in the energy between the two involved levels.

Answer and Explanation:

According to Bohr's theory, the electrons around the nucleus are held in fixed energy shells.

When an electron goes from a lower energy state to a...
