Question

According to the Heisenberg uncertainty principle, what fundamental limitation exists when studying electrons?
Options
A Electrons cannot exist in quantized energy states
B It is impossible to know both the exact momentum and exact location of an electron simultaneously
Correct Answer
C Electrons must always be described as particles, never as waves
D The energy of an electron cannot be determined under any circumstances
Correct Answer

Option B is the correct answer.

Detailed Explanation

Werner Heisenberg's uncertainty principle states that it is inherently impossible to simultaneously determine both the exact momentum and the exact position of an electron. This limitation arises from the dual wave-particle nature of matter.

Hint

Consider the consequence of the wave properties of matter on our ability to measure both location and momentum precisely.
