The Bohr model of the atom proposed that electrons move in:
A
Fixed circular orbits with quantized energy levels
B
Random paths
C
Straight lines only
D
Elliptical orbits with continuous energy
Correct Answer: Option A — Fixed circular orbits with quantized energy levels
Explanation:
Niels Bohr proposed that electrons orbit the nucleus in specific, fixed circular paths with quantized energy levels, and electrons can jump between these levels by absorbing or emitting discrete amounts of energy.
