C2.2

• What is a chemical property?

  A characteristic of a substance that can only be determined by studying its chemical reactions.
• How do metals and non-metals differ in terms of electron behavior?

  Metals lose electrons to form positive ions, while non-metals gain electrons to form negative ions.
• What happens when metal oxides and non-metal oxides dissolve in water?

  Metal oxides produce alkaline solutions, while non-metal oxides produce acidic solutions.
• What are the physical properties of metals and non-metals?

  • Metals: Malleable, ductile, conductors of heat and electricity
  • Non-metals: Brittle, insulators
• How can you test whether an oxide is from a metal or a non-metal?

  By dissolving it in water and using a universal indicator to observe the color change.
• What color indicates a metal oxide solution when tested with a universal indicator?

  Blue
• What color indicates a non-metal oxide solution when tested with a universal indicator?

  Red
• How do metals and non-metals react with each other?

  Metals do not react with each other but form alloys, while non-metals react to produce compounds that consist of molecules.
• Where are metals and non-metals located in the Periodic Table?

  Metals are on the left-hand side, and non-metals are on the right-hand side.
