According to the Heisenberg Uncertainty Principle A) an electron can never appear in the exact same position twice. B) electrons must always absorb energy when moving to higher quantum levels. C) an electron has a charge of 1.602 × 10^-19 C. D) s orbitals are spherical in nature. E) you cannot accurately know both the position and momentum of an electron at the same time.

Question

Quizplus · Accepted Answer

The Heisenberg Uncertainty Principle states that it is impossible to know both the exact position and momentum of a particle (such as an electron) simultaneously. This is sometimes expressed mathematically as Δx * Δp ≥ h/4π, where Δx is the uncertainty in position, Δp is the uncertainty in momentum, and h is Planck's constant. Therefore, choice E is the correct answer.
