Key ideas in Metals: From Shiny Rocks to Superpowers
- Metals are defined by luster, conductivity, and malleability
- Non-metals are typically brittle or gaseous
- Metals occupy the left and center of the table
- Non-metals (gases) are clustered on the far right
- Surface oxidation can hide metallic luster
- Malleability is a more definitive test than hardness
- Electrical conductivity is the final 'club' requirement
- Locating metals versus non-metals (gases) on the periodic table
- Metallic bonding involves delocalized electrons
- Loose electrons are the reason for conductivity and flexibility
- Proving a material is a metal through a sequence of physical tests
- Understanding the 'why' behind metal behavior (electron sharing)
- Conductivity allows energy flow
- Malleability allows shaping without breaking
- Luster is the ability to reflect light
- Matching the physical property to the practical 'real world' result
