Question

select the correct answer. how was bohr’s atomic model different from rutherford’s atomic model?
a. bohr’s model accounted for electrons that have different charges.
b. bohr’s model could explain the structure of the nucleus.
c. bohr’s model showed that electron orbits had distinct radii.
d. bohr’s model could explain the wave nature of electrons.
e. bohr’s model proved that atoms are unstable in nature.

Explanation:

• Option A: Electrons have the same charge, so this is incorrect.
• Option B: Neither Bohr's nor Rutherford's model explained the nucleus structure (that came later with quantum mechanics and nuclear physics), so B is wrong.
• Option C: Bohr's model introduced quantized electron orbits with distinct radii, while Rutherford's model had electrons moving in any orbits around the nucleus. This is a key difference.
• Option D: The wave nature of electrons was explained by the de Broglie hypothesis and later quantum mechanics, not Bohr's model, so D is incorrect.
• Option E: Bohr's model actually helped explain atomic stability (electrons in specific orbits don't radiate energy and fall into the nucleus), so E is wrong.

Answer:

C. Bohr’s model showed that electron orbits had distinct radii
