Question

question 23 (1 point)
which of the following best describes an electron using the quantum mechanical model?
a standing wave like the vibration of a guitar string
a particle that circles the nucleus in orbits like planets around the sun
a wave that circles the nucleus in orbits like planets around the sun
none of the above

Explanation:

• In the quantum mechanical model, electrons are described as standing waves (wave - like behavior) in the electron cloud around the nucleus.
• The planetary model (electron as a particle or wave circling the nucleus in orbits like planets around the sun) is from the Bohr model, not the quantum mechanical model.

Answer:

a standing wave like the vibration of a guitar string
