Question

Which statement about electrons & atomic orbitals is NOT true?

Answer 1

Options:

An electron has the same amount of energy in all orbitals.

An orbital can contain a maximum of two electrons.

An electron cloud represents all the orbitals in an atom.

An atom’s lowest energy level has only one orbital.

Answer: An electron has the same amount of energy in all orbitals

Explanation: An electron has the same amount of energy in all orbitals is the statement that is not true and all other statements are true.

In an atom, we have three subatomic particles which are protons, neutrons, and electrons. Electrons cannot have the same amount of energy in all orbitals because they revolve in orbits around the nucleus. That means that level of energy in electrons is always different in all orbitals.
