Which of the following best describes atomic orbitals?
A
Fixed paths that electrons follow around the nucleus
B
Points in space where electrons are always located
C
Regions in space where there is a high probability of finding an electron
D
Physical shells that contain protons and neutrons
Verified step by step guidance1
Understand that atomic orbitals are a concept from quantum mechanics used to describe the behavior of electrons in an atom.
Recall that electrons do not move in fixed paths like planets around the sun; instead, their positions are described by probability distributions.
Recognize that an atomic orbital represents a region in space where there is a high probability of finding an electron, not a definite path or fixed point.
Eliminate options that describe electrons as following fixed paths or being at fixed points, as these do not align with the quantum mechanical model.
Note that protons and neutrons are located in the nucleus, not in orbitals, so orbitals cannot be physical shells containing these particles.
