Question 9 • Physics

Which statement is part of Bohr's atomic model?

Answer
A
Electrons exist as waves and clouds of probability with specific orbits and shapes.
B
Electrons orbit the nucleus in narrow ellipses, like how the planets orbit the Sun.
C
Electrons absorb or emit light when they change energy levels.
D
Electrons with the highest energy are found with orbits of the smallest radius.

Explanation

In Bohr’s model, electrons occupy specific, quantized energy levels. An electron absorbs or emits light when it moves between those levels, with the light’s energy matching the difference between them. Therefore, the correct statement is “Electrons absorb or emit light when they change energy levels.”
