What in the world is IONIZATION ENERGY?!?

The video tutorial explains ionization energy, the energy required to remove an electron from an atom. It discusses the trends of ionization energy on the periodic table, noting that it increases as you move up a group and from left to right across a period. The video uses examples to illustrate these trends, emphasizing the role of energy levels and the number of protons in determining ionization energy. It also highlights that these trends are not absolute laws and have exceptions.
