Properties of Metals and Non-Metals

The video tutorial covers the properties of metals and non-metals, focusing on ductility, thermal and electrical conductivity, and sonority. It includes activities demonstrating thermal conductivity and the chemical properties of metals and non-metals. The tutorial explains that while physical properties can help differentiate metals from non-metals, chemical properties provide a clearer distinction. Examples of metals like gold, copper, and silver, and non-metals like carbon and iodine, are discussed to illustrate these properties.

Which metal is known to be the most ductile?

• Copper

• Silver

• Aluminum

• Gold

Which metals are considered good conductors of heat?

• Copper and Lead

• Gold and Silver

• Silver and Copper

• Lead and Mercury

What property allows metals to conduct electricity?

• Sonorous

• Thermal Conductivity

• Ductility

• Electrical Conductivity

What is the term for metals that produce sound when hit?

• Ductile

• Sonorous

• Conductive

• Lustrous

Which of the following is NOT a general property of non-metals?

• Non-conductors of electricity

• Non-sonorous

• Non-conductors of heat

• High boiling points

Which non-metal is known to be lustrous?

• Phosphorus

• Sulfur

• Iodine

• Carbon

Why can't we differentiate metals from non-metals based solely on physical properties?

• Because metals and non-metals have the same density

• Because all non-metals are soft

• Because some non-metals have high melting points

• Because all metals are hard

What type of oxides do metals produce?

• Acidic

• Amphoteric

• Neutral

• Basic
