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 fundamentally impossible to precisely know both the position and the momentum of a particle (like an electron) at the same time. The more accurately one is measured, the less accurately the other can be known. Option A describes the Pauli Exclusion Principle. Option B is a definition of an element. Option D describes Hund's Rule.

Hint

The Heisenberg Principle deals with the fundamental limits of measurement for certain pairs of physical properties.
