Periodic Trends

• Ionization energy is the amount of energy required to remove an electron from an atom

• Can be predicted with Coulombs Law
• Shown through Photoelectron Spectroscopy
• The more electrons an atom has, the less attracted they are to an individual electron
• If it has a positive charge, it wants to get rid of that electron to be made whole
• Electrons closer to the nucleus experience greater attraction force
• We mostly just look at the first ionization energy, but there are tables showing the ionization energies of every electron an atom can hold
  • These are called Successive Ionization Energy Tables
