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 simultaneously know both the exact position and the exact momentum (or velocity) of a particle, particularly an electron, with perfect accuracy. The more precisely one property is known, the less precisely the other can be known.Let's look at the other options:A. This statement describes the Pauli Exclusion Principle.B. This is the definition of an element.D. This statement describes Hund's Rule.

Hint

The Heisenberg Uncertainty Principle is a fundamental concept in quantum mechanics that deals with the limitations of measurement for certain pairs of physical properties.
