Metallic solids

Definition

Metallic solids are types of solids composed of metal atoms held together by a sea of delocalized electrons. They typically exhibit high electrical and thermal conductivity, malleability, and ductility.

5 Must Know Facts For Your Next Test

1. Metallic bonding involves the attraction between free-floating electrons and positively charged metal ions.
2. Metallic solids have high melting and boiling points due to strong metallic bonds.
3. They are good conductors of electricity because the delocalized electrons can move freely.
4. The malleability and ductility of metallic solids arise from their ability to deform under stress without breaking bonds.
5. Examples include elements like iron, copper, and gold.
