GCSE Chemistry - Metallic Bonding #20

The video tutorial explains metallic bonding, a type of bonding between metal atoms, and its role in giving metals their characteristic properties. It describes the structure of metallic bonding, where atoms form a giant structure with delocalized electrons, leading to strong electrostatic attractions. This structure gives metals high melting and boiling points, conductivity, and malleability. The tutorial also covers alloys, which are mixtures of metals or metals with non-metals, and how they differ from pure metals by having disrupted structures that prevent layers from sliding, making them harder.

What is metallic bonding and how does it contribute to the properties of metals?

Explain the role of delocalized electrons in metallic bonding.

What are some common properties of metals that result from metallic bonding?

How do alloys differ from pure metals in terms of structure and properties?

Describe how the structure of alloys affects their hardness compared to pure metals.
