Question

"It is impossible to simultaneously exactly know both the position and momentum of an electron in an atom" is:

A. Hund's rule
B. Pauli's exclusion principle
C. deBroglie's hypothesis
D. Heisenberg's Uncertainty Principle

Answer 1

The correct answer is D. Heisenberg's Uncertainty Principle.

Step-by-step explanation:

The correct answer is D. Heisenberg's Uncertainty Principle.

The Heisenberg Uncertainty Principle states that it is impossible to simultaneously determine both the position and momentum of a particle, such as an electron, with arbitrary precision. This principle is a fundamental concept in quantum mechanics and was developed by German physicist Werner Heisenberg. The principle states that the product of the uncertainties in position and momentum is always larger than or equal to Planck's constant divided by 2.
