  3. Metals conduct electricity.

  1. Reasons: Zinc oxide can react with both acid and bases, that’s why it is considered as amphoteric oxide.

  2. Only more reactive compound can displace less reactive compound. Since, non-metals are less reactive than hydrogen. So, they can’t displace hydrogen from diluted acids.

  3. Metals have free electron through which electricity can flow easily. That’s why metal conducts electricity.
