Question

The third line of the Balmer series, in the emission spectrum of the hydrogen atom, is due to the transition from the ______.

Options

• fourth Bohr orbit to the first Bohr orbit

• fifth Bohr orbit to the second Bohr orbit

• sixth Bohr orbit to the third Bohr orbit

• seventh Bohr orbit to the third Bohr orbit

Answer 1

The third line of the Balmer series, in the emission spectrum of the hydrogen atom, is due to the transition from the fifth Bohr orbit to the second Bohr orbit.

Explanation:

For the emission spectrum Balmer series n₁ = 5, n₂ = 2 for the third line.
