Which of the following best describes the difference between an orbit and an orbital in atomic theory?
A
An orbit is a fixed circular path around the nucleus, while an orbital is a region of space where there is a high probability of finding an electron.
B
An orbit and an orbital are both fixed paths that electrons follow around the nucleus.
C
An orbit refers to the path of a neutron, while an orbital refers to the path of an electron.
D
An orbit is a region of space with a high probability of finding a proton, while an orbital is for electrons.
Verified step by step guidance1
Understand that in early atomic models, such as the Bohr model, an 'orbit' was described as a fixed, circular path that an electron follows around the nucleus.
Recognize that modern quantum mechanics replaced the concept of fixed orbits with 'orbitals,' which are not paths but rather regions in space where there is a high probability of finding an electron.
Note that an orbital is defined by a wavefunction and can have various shapes (spherical, dumbbell-shaped, etc.), reflecting the electron's probable location rather than a precise trajectory.
Distinguish that orbits imply a definite path and position at any time, which contradicts the Heisenberg uncertainty principle, while orbitals accommodate this principle by describing probabilities.
Conclude that the best description is: an orbit is a fixed circular path around the nucleus, while an orbital is a region of space where there is a high probability of finding an electron.
