Questions: 10 | Attempts: 86 | Last updated: Sep 22, 2025

Sample Question 1
What is electron spectroscopy?

A method used to determine the quantity of electrons in a substance

A technique employed to study the energy levels and transitions of electrons

A process used to measure the mass of electrons

A procedure to investigate the electrical conductivity of electrons

Sample Question 2
Which series in electron spectroscopy corresponds to transitions to the energy level with the principal quantum number (n) equal to 5?

Lyman series

Balmer series

Paschen series

Pfund series

Sample Question 3
What is the general formula for calculating the wavelength of the spectral lines in electron spectroscopy?

1/λ = R(1/n₁² - 1/n₂²)

1/λ = R(n₁² - n₂²)

1/λ = R(n₁ - n₂)

1/λ = R(m/n)
