Periodicity
Students analyse the trends in physical properties of Period 3 elements, including atomic radius, ionisation energy, and melting points. They will link these macroscopic trends to atomic structure.
About This Topic
Students analyse the trends in physical properties of Period 3 elements, including atomic radius, ionisation energy, and melting points. They will link these macroscopic trends to atomic structure.
Key Questions
- Why does atomic radius decrease across Period 3?
- How do the melting points of Period 3 elements reflect their structure and bonding?
- What causes the general increase in first ionisation energy across a period?
