Identify the incorrect statement from the following.
(A) A circular path around the nucleus in which an electron moves is proposed as Bohr's orbit.
(B) An orbital is the one electron wave function (

Ψ

) in an atom.
(C) The existence of Bohr's orbits is supported by hydrogen spectrum.
(D) Atomic orbital is characterised by the quantum numbers n and

l

only

(A)A circular path around the nucleus in which an electron moves is proposed as Bohr's orbit.
(B)An orbital is the one electron wave function ( $Ψ$ ) in an atom.
(C)The existence of Bohr's orbits is supported by hydrogen spectrum.
(D)Atomic orbital is characterised by the quantum numbers n and $l$ only✓ Correct

Answer: (D)

Solution

An atomic orbital is fully characterized by three quantum numbers:

n

(principal),

l

(azimuthal), and

m

(magnetic). Statement (D) incorrectly states that only

n

and

l

characterize an orbital, omitting

m

. The other statements are correct: Bohr proposed circular orbits (A), an orbital is the wave function

Ψ

(B), and the hydrogen spectrum supports Bohr's model (C).
