Question

The Heisenberg Principle states that:

• 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
• 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

Answer 1

The correct option is C It is impossible to determine accurately both the position and momentum of an electron simultaneously

According to Heisenberg's Principle: It is impossible to determine accurately both the position and momentum of an electron simultaneously.
Mathematically,
$\Delta x\times \Delta P\ge \frac{h}{4\pi }$
