Question

How does Bohr's atomic model differ from Thomson's:

A) Inclusion of electrons
B) Quantized energy levels
C) Presence of a nucleus
D) Electron cloud model

Answer 1

Bohr's atomic model differs from Thomson's in terms of the inclusion of electrons, quantized energy levels, and the presence of a nucleus.

Step-by-step explanation:

Bohr's atomic model differs from Thomson's in the following ways:

1. Inclusion of electrons: Bohr's model includes electrons orbiting the nucleus in specific energy levels, while Thomson's model did not describe the existence or behavior of electrons.
2. Quantized energy levels: In Bohr's model, electrons can only exist in certain energy levels or orbits, while Thomson's model did not account for quantized energy levels.
3. Presence of a nucleus: Bohr's model includes a central nucleus containing protons and neutrons, while Thomson's model did not specify the presence of a nucleus.

Therefore, Bohr's atomic model provides a more detailed and accurate description of the structure of an atom compared to Thomson's model.
