What is Coulomb's Law?
This is what PES stands for.
What is photoelectron spectroscopy?
This is the repulsion imposed on valence electrons by any core electrons between them and the nucleus.

This is the unit that the mass of an individual atom or particle is reported in.
What is atomic mass units (amu).
This lab technique is used to separate liquids in a mixture based on the differing volatilities of the liquids.
What is distillation?
This chemist discovered that atoms contain a small, dense, positively-charged nucleus.
Who is Ernest Rutherford?
This is what is shown on the x-axis of a PES graph.
What is binding energy (ionization energy)?
This is the energy required to remove an electron from an atom or ion in its gaseous state.

This is the periodic trend for atomic radius.
What is "increases down a group" and "increases across a period"?
When finding the average atomic mass of an element, you multiple the mass of each isotope by this value which can be found on a mass spectroscopy graph.
