Chemistry - Periodic Table - Metals, non-metals, and metalloids - Property Tester: Metals vs Non-metals

An interactive comparison lab. Show 3 sample elements: Iron (metal), Sulfur (non-metal), Silicon (metalloid). Run 5 virtual tests on each: 1) APPEARANCE: Iron = shiny/lustrous. Sulfur = dull/powdery. Silicon = shiny but not like metal. 2) MALLEABILITY (hammer test): Iron = flattens (malleable). Sulf
