  • They are malleable,
  • Lustrous
  • Good conductors of electricity and heat.
  • They lose their electrons to form positively charged ions.
  • They form basic oxides by combining with oxygen.

Oxides which show basic and acidic properties are called amphoteric oxide. Example, zinc oxide and aluminium oxide.

What is metallurgy?

The process of extracting metal from ore and refining it is called metallurgy.

What is corrosion?

Corrosion is a phenomenon where a metal like iron is exposed to moistened air for a long period of time.

What are non-metals?

Non-metals are not ductile and malleable. Excluding graphite, all non-metals are bad conductors of electricity and heat. They gain electrons to form negative ions when they react with metals. Non-metals form hydrides by reacting with hydrogen. They can form oxides which are either neutral or acidic.
