Study Notes
Properties of Metals
- Metals are typically characterized by their luster, conductivity, ductility, and malleability.
- Ductility refers to the ability of metals to be stretched into wires, a result of their atomic structure and bonding.
Metallic Bonding
- Metallic bonds involve the sharing of free electrons among a lattice of metal atoms, resulting in strong interatomic attraction.
- This bonding leads to properties such as electrical and thermal conductivity due to the mobility of electrons.
Definition of Metals in Physics
- In physics, metals are generally defined as elements that are good conductors of electricity and heat and exhibit ductility and malleability.
Nonmetals Becoming Metallic
- Nonmetals can exhibit metallic properties under certain conditions, such as high pressure or when they are in specific chemical states or forms.
Transition from Metal to Nonmetal
- Some materials considered metals can display nonmetallic characteristics when they undergo structural changes, or when they are combined with specific nonmetallic elements.
Conductivity Temperatures
- A typical temperature at which a substance begins to conduct electricity dramatically is associated with its state (solid, liquid) and structure, often aligning with higher temperatures for nonmetals.
Lustrous Metallic Substances
- A substance that is freshly prepared, polished, or fractured will show a lustrous appearance, high conductivity, and properties such as ductility and malleability; these are hallmark features of metals.
