Study Notes
Periodic Trends
- Periodic trends refer to patterns in properties of elements that repeat periodically across the periodic table.
Atomic Radius
- Atomic radius increases as you move down a group (vertical column) due to the addition of more energy levels.
- Atomic radius decreases as you move across a period (horizontal row) due to increasing nuclear charge pulling the electrons closer to the nucleus.
Ionic Radius
- Cations (positively charged ions) are smaller than their parent atoms.
- Anions (negatively charged ions) are larger than their parent atoms.
- Ionic radius follows the same pattern as atomic radius, increasing down a group and decreasing across a period.
Ionization Energy
- Ionization energy is the energy required to remove an electron from an atom to form a cation.
- Ionization energy decreases down a group due to increased atomic size and shielding effect.
- Ionization energy increases across a period due to increased nuclear charge, making it more difficult to remove electrons.
Electron Affinity
- Electron affinity is the energy released when an electron is added to an atom to form an anion.
- Electron affinity generally increases across a period from left to right due to increased nuclear charge.
- Electron affinity shows irregularities in noble gases.
