Study Notes
Physical Properties of Metals
- Ductility refers to the ability of metals to be drawn into wires without breaking.
- Malleability describes the capacity of metals to be hammered or rolled into thin sheets.
- Metals are characterized by their high density and typically possess high melting and boiling points.
- Commonly known as electrical conductors, metals effectively conduct electricity and heat.
- Metals exhibit luster, providing a shiny appearance; this is often described as a metallic luster.
- Most metallic elements are found on the left side of the periodic table, with most elements classified as metals.
Physical Properties of Non-metals
- Non-metals are located on the far right-hand side of the periodic table.
- They are generally dull, lacking the shine seen in metals, and do not possess malleability or ductility.
- Non-metals have low density and typically feature low melting and boiling points.
- Classified as electrical insulators, non-metals do not conduct electricity or heat effectively.
- The term brittle describes the tendency of non-metals to break easily rather than deform.
- Non-metals can exist in various states of matter: solids, liquids, and gases.
Additional Properties
- Metals are sonorous, producing a ringing sound when struck.
- Heat conductors permit efficient heat transfer, contrasting with heat insulators, which slow heat transfer.
- Most metallic elements are primarily found in the solid state, while non-metals can be found in all three states of matter.
