Jumping of electrons into orbit 1 generates the series known as___________________?
Show answer Hide answer
Answer: A. Lyman
Explanation
The series of spectral lines corresponding to electrons falling from higher energy levels to the innermost orbit (n=1) in the hydrogen atom is called the Lyman series. Transitions terminating at the ground state emit high-energy photons located primarily within the ultraviolet region. Each hydrogen spectral series is named after the physicist who discovered or studied that specific electronic transition group. The Bohr model of the atom describes quantized electron orbits corresponding to specific principal quantum numbers. Ultraviolet radiation consists of electromagnetic waves with frequencies higher than visible light but lower than X-rays. Energy emitted during electron transitions equals the exact difference between initial and final orbital energy levels.
Option B refers to the Paschen series, which involves electron transitions ending at the third orbit (n=3). Option C suggests the Pfund series, characterized by electron transitions terminating at the fifth orbit (n=5). Option D lists the Brackett series, which corresponds to electron transitions falling back to the fourth orbit (n=4).
