Question

The Heisenberg Principle states that
Options
A no two electrons in the same atom can have the same set of four quantum numbers.
B two atoms of the same element must have the same number of protons.
C it is impossible to determine accurately both the position and momentum of an electron simultaneously.
Correct Answer
D electrons of atoms in their ground states enter energetically equivalent sets of orbitals singly before they pair up in any orbital of the set.
Correct Answer

Option C is the correct answer.

Detailed Explanation

The Heisenberg Uncertainty Principle, formulated by Werner Heisenberg, states that it is impossible to precisely determine both the position and the momentum of a particle (like an electron) simultaneously.Option A describes the Pauli Exclusion Principle.Option B describes a fundamental property of elements (atomic number).Option D describes Hund's Rule of maximum multiplicity for electron configurations.

Hint

The Heisenberg Principle is a fundamental concept in quantum mechanics that deals with the limitations of measurement.
