Periodic Trends

There are a couple of properties of atoms that have characteristic trends. We need to be able to discuss these trends in terms of atomic structure, specifically the forces acting within an atom that affect these properties.

ELECTRONEGATIVITY

Atomic Structure - Forces of Attraction and Repulsion

In trying to understand electron configurations and periodic trends, we need to understand the forces inside an atom:

On 2 June, we looked at radius in a bit more detail:

Redox Equations

This year, we need to be aware that some oxidants and reductants make different products depending upon the conditions - acidic, neutral or alkaline.
