Study Notes
Variation of atomic radius
- Atomic radius varies across the periodic table (left to right).
- The number of shells remains constant across a period.
Shielding Effect
- Atomic number increases, the number of inner electrons decreases
- Shielding effect also decreases, and atomic radius decreases.
Nuclear Charge
- Atomic number increases, nuclear charge increases.
- Atomic radius decreases.
Number of Shells
- Moving down a group, the number of shells increases.
- Atomic radius increases.
Trends in a Group
- Moving down a group, the nuclear charge increases and atomic radius increases.
