Atomic Structure and the Periodic Table · Atomic Structure
Electronic Configuration and Periodicity
Mapping electrons in orbitals and identifying trends across the periodic table.
Key Questions
- 1How does the arrangement of electrons determine the chemical personality of an element?
- 2Why do atomic radii decrease as we move across a period despite increasing mass?
- 3What evidence do we have for the existence of sub-shells and orbitals?
