Properties and States of Metals and Non-Metals

The video tutorial covers the classification and physical properties of metals and non-metals. Metals are generally solid, shiny, good conductors, ductile, and malleable, while non-metals are often gases, dull, insulators, and brittle. Exceptions like mercury and graphite are also discussed.

Why are copper wires commonly used in electrical applications?

• They are cheap

• They are lightweight

• They are colorful

• They are good conductors

What does the term 'ductility' refer to in metals?

• Ability to resist corrosion

• Ability to conduct electricity

• Ability to be drawn into wires

• Conductivity

• Brittleness

What is a typical state of non-metals at room temperature?

• Gas

• Liquid

• Plasma

Why are non-metals generally considered dull?

• They absorb light

• They do not reflect light well

• They are transparent

• They are opaque

Which of the following is an exception where a non-metal can conduct electricity?

• Plastic
