Metals, Non-Metals & Metalloids

Name a property of non-metals.

• Non-metals are brittle.

• Non-metals are good conductors of electricity.

• Non-metals are malleable.

• Non-metals have high melting points.

What is malleability?

• The ability of a material to conduct electricity.

• The ability of a material to be stretched into a wire without breaking.

• The ability of a material, especially metals, to be hammered or pressed into shape without breaking.

• The ability of a material to resist deformation under stress.

What is brittleness?

• The ability of a material to deform under stress without breaking.

• The tendency of a material to break or shatter easily when subjected to stress.

• The property of a material to conduct electricity efficiently.

• The capacity of a material to absorb energy before fracturing.

Which element is known to be magnetic?

• Copper

• Iron

• Gold

• Aluminum

How do metals typically react with acids?

• They do not react at all.

• They produce oxygen gas and a base.

• They produce hydrogen gas and a salt.

• They react to form a metal oxide.

What is the significance of the term 'dull' in classifying metals?

• It indicates that the element is a metal due to its unique properties.

• If an element is dull, it is not classified as a metal, as metals typically have a shiny luster.

• Dull elements are always found in nature as pure metals.

• Dullness is a characteristic of all elements, not just metals.

What is a metal?

• A type of element that is typically a good conductor of heat and electricity, malleable, ductile, and has a shiny appearance.

• A non-metal element that is usually brittle and poor in conductivity.

• An element that is always found in a gaseous state at room temperature.

• A type of compound that contains both metals and non-metals.

Name a property of metals.

• Metals are malleable.

• Metals are brittle.

• Metals are insulators.

• Metals are transparent.

What is ductility?

• The ability of a material to be stretched into a wire without breaking.

• The ability of a material to resist deformation under stress.

• The ability of a material to conduct electricity.

• The ability of a material to absorb heat without changing temperature.

What is the difference between metals and non-metals in terms of conductivity?

• Metals are poor conductors of heat and electricity, while non-metals are good conductors.

• Metals are good conductors of heat and electricity, while non-metals are poor conductors.

• Both metals and non-metals are good conductors of heat and electricity.

• Non-metals are better conductors than metals.
