Which of the following factors affect the ionization energy of an atom?
Which of the following trends is observed for ionization energy across a period in the periodic table?
Study Notes
Ionization Energy
- Ionization energy is the minimum energy required to remove the outermost electron from a neutral atom in its ground state.
Factors Affecting Ionization Energy
- Atomic radius: as atomic radius decreases, ionization energy increases
- Electron shielding: effective nuclear charge increases as electron shielding decreases, resulting in higher ionization energy
- Nuclear charge: as nuclear charge increases, ionization energy increases
Trends in Ionization Energy
- Across a period, ionization energy generally increases from left to right due to increasing nuclear charge and decreasing atomic radius.
