Understanding Metallic Bonding and Alloys

What is the primary reason metals can conduct electricity effectively?

• They have a regular atomic structure.

• They have a high density.

• They contain delocalized electrons.

• They are malleable.

Why are metals considered malleable?

• They are good conductors of heat.

• They contain delocalized electrons.

• Their layers can slide over each other.

• They have a high melting point.

What is an alloy?

• A metal with a regular atomic structure.

• A mixture of two or more elements, often metals.

• A pure metal with a high melting point.

• A metal that is a good conductor of electricity.

What is the main advantage of creating alloys?

• They prevent layers from sliding, making them harder.

• They have a lower melting point.

• They are more malleable than pure metals.

• They conduct electricity better than pure metals.

Which element is primarily used in the composition of steel?

• Vanadium

• Iron

• Chromium

• Carbon
