This project was preformed to supply Libretext Authors with videos on General Chemistry topics which can be used to enhance their projects. Also, these videos are meant to act as a learning resource for all General Chemistry students.

The ionization energy is the energy needed to remove an electron from an atom in the gas phase. T he first ionization energy, I1, is the energy required to remove an electron from a neutral atom in its ground state. The second ionization energy, I2, is the energy needed to strip an electron from a gaseous ion with a charge of 1+. It is possible keep removing electrons to produce a third, fourth ect. Ionization energies. Each succeeding ionization requires more energy. For the second ionization you are removing a negatively charged e- from a positive charge. In general, as Zeff increases there is stronger interaction between the nucleus and the electrons. This means as Zeff increases the ionization energy also increases.
