This video is about The Photoelectron Spectroscopy, and discusses in details the generation and interpretation of photoelectron spectra of atoms.

Moreover, in this video I discuss the photoelectric effect and hoe to calculate the kinetic energy of electrons removed using the energy of incident light used and the binding energy if electrons.

In this video I discuss in details the photoelectric spectra of the following elements:

  • Sodium, Na
  • Carbon, C
  • Oxygen, O
  • Neon, Ne
  • Scandium, Sc

Moreover, I discuss why 4s orbital is filled before 3d orbitals and why electrons are removed from 4s before 3d.

Students studying Chemistry at different levels could highly benefit from this video.
