Metals vs Non-Metals
金属与非金属
Description
Compare the physical and chemical properties of metals and non-metals, explaining metallic properties (malleability, lustre, conductivity) and how position in the periodic table predicts reactivity
Mastery Evidence
- Lists physical properties typical of metals (shiny, malleable, good conductor) and non-metals
- Explains why metals are used in wires, cookware, and construction based on their properties
- Uses the periodic table to predict whether an element is likely to be reactive or unreactive
- Explains what lustre and malleability mean in terms of real-world observations
Assessment Prompt
If your child had an unknown substance that was shiny, could be bent without breaking, and conducted electricity, could they identify it as likely a metal and explain how each property points to that conclusion?
