Binding Energy

The energy required to remove an electron from an atom, ion, or subshell

Electron Repulsions

The electrostatic force that pushes electrons away from each other due to their identical negative charges

Peak Position on PES (x-axis)

The amount of binding energy at each subshell

Peak Height on PES (y-axis)

Represents the number of electrons in that shell

Coulomb’s Law

Electrostatic force is proportional to charge product and inversely proportional to distance squared.

Electronegativity

an atom's ability to attract shared electrons toward itself in a chemical bond

Electron Affinity

the energy change that occurs when an electron is added to a neutral gaseous atom to form a negative ion
