Specification Point 1.20:
Understand how to use electrical conductivity and the acid-base character of oxides to classify elements as Metals or Non-metals
Metals vs Non-Metals
| Metals | Non-metals |
|---|---|
| Basic oxides (alkaline) | Acidic oxides (acidic) |
| Good conductors of electricity | Poor conductors of electricity |
| High melting and boiling point | Low melting and boiling point |
| Malleable | Flaky |
Specification Point 1.21:
Identify an element as a metal or a non-metal according to its position in the periodic table
Identifying Metals from Periodic Table Position
