What are the physical properties of a typical metal?

  1. Strong (hard to break)
  2. Malleable (can be bent or hammered into shape)
  3. Ductile (can be shaped into wires)
  4. Good conductors of electricity and heat
  5. High melting and boiling points
  6. Dense
  7. Shiny

Where on the periodic table are transition metals found?

Answer in your head, out loud, or on paper, then tap the card to flip.

Give 3 special properties of transition metals (properties that normal metals don’t have).

  1. They make good catalysts. For example an iron catalyst us used in the Haber process to produce ammonia.
  2. Their ions are often coloured and so they can form colourful compounds.
  3. They can have more than one ion. For example copper can form Cu+ and Cu2+ ions.

Do non-metals form positive or negative ions when they react?

Negative ions.

What are the physical properties of most non-metals?

  1. Brittle (snap easily)
  2. Dull (not shiny)
  3. Lower melting and boiling points
  4. Poor conductors of electricity
  5. Lower density
