Ionization Energy Notes

Charge of Ions

• Elements can have a charge of 2+, but this doesn't necessarily mean the energy required to remove an electron is 2+.

Francium's Ionization Energy

• Francium has the lowest ionization energy, making it highly reactive.

Factors Affecting Ionization Energy

• Adding more electrons and protons increases attraction, thus affecting ionization energy.

Elements with High Ionization Energies

• Some elements have very high ionization energies due to strong attraction between electrons and protons.

Ionization Energy Trend (Left to Right)

• Ionization energy increases from left to right across the periodic table.
