Question 1:

According to the Bohr model of the atom, electrons:

Explanation: According to the Bohr model of the atom, electrons exist in discrete energy levels around the nucleus. These energy levels are quantized, meaning electrons can only occupy certain allowed energy states.

Question 2:

When an electron in an atom transitions from a higher energy level to a lower energy level, it:

Explanation: When an electron in an atom transitions from a higher energy level to a lower energy level, it emits a photon of specific energy. The energy of the emitted photon corresponds to the energy difference between the initial and final energy levels.

Question 3:

The principal quantum number (n) in the Bohr model represents:

Explanation: In the Bohr model, the principal quantum number (n) represents the energy level of an electron. Higher values of n correspond to higher energy levels farther from the nucleus.

Question 4:

Which of the following statements about the Bohr model is correct?

Explanation: The correct statement is that the Bohr model does not account for the wave-particle duality of electrons. The model treats electrons as classical particles in specific orbits, neglecting their wave-like properties.

Question 5:

Electron transitions in atoms can result in the emission or absorption of photons. Which of the following determines the energy of the emitted or absorbed photons?

Explanation: The energy of the emitted or absorbed photons is determined by the energy difference between the initial and final energy levels of the electron undergoing the transition. The specific energy levels involved determine the frequency (and hence energy) of the emitted or absorbed photons.
