Coloumb’s Law
Like charges repel; opposite charges attract. The force is proportional to the magnitude of the charges and inversely proportional to the square of the distance between them.
Ionization energy
Position of the peaks in the PES graph horizontally denotes which shell the electrons are in; size of the peaks vertically denotes how many electrons are in that shell.
Photoemmission spectroscopy (PES)
Photons of a certain wavelength are fired into atoms of an element and either knock off electrons or don’t depending on whether they exceed the requisite ionization energy.
Equation describing coloumb’s law
F = K q1 q2 / R²
