Which of the following rules states that it is impossible to determine simultaneously the exact position and exact momentum of an electron?
Aufbau's principle
de Broglie's hypothesis
Heisenberg uncertainty principle
Pauli's exclusion principle
Solution
According to Heisenberg's uncertainty principle, "it is impossible to calculate the position and momentum of a small moving object like an electron simultaneously and accurately." The principle only applies to microscopic particles and not to macroscopic particles.
