The periodic table showcases fundamental patterns in atomic properties, with trends in electronegativity across periodic table, covalent radii changes in periodic table groups, and factors affecting ionisation energy in elements following predictable patterns based on atomic structure and nuclear forces.
- Electronegativity demonstrates clear trends, decreasing down groups due to electron shielding and increasing across periods with greater nuclear charge
- Covalent radii exhibit systematic changes, growing larger down groups and smaller across periods due to nuclear attraction effects
- Ionisation energy patterns reflect atomic structure, decreasing down groups due to electron shell distance and increasing across periods from stronger nuclear attraction
- These properties are interconnected and directly influenced by atomic structure and electron configuration
- Understanding these trends is crucial for predicting chemical behavior and bonding patterns
