Study Notes
Physical Properties of Metals
- Excellent conductors of electric current and heat, making them useful in electrical applications.
- Characterized by high luster, giving them a shiny appearance.
- Ductility allows metals to be drawn into wires without breaking.
- Malleability enables metals to be hammered or rolled into thin sheets.
Chemical Properties of Metals
- Typically react by losing electrons during chemical reactions, indicating a tendency to form positive ions.
- Metals exhibit high reactivity; some, like alkali metals, react vigorously with water and air.
Physical Properties of Nonmetals
- Poor conductors of heat and electric current, contrasting with metals.
- Solids tend to be dull and brittle, breaking easily rather than deforming.
- Generally possess lower densities compared to metals, making them lighter.
Chemical Properties of Nonmetals
- Nonmetals tend to gain or share electrons during chemical reactions, leading to the formation of negative ions or covalent bonds.
Transuranium Elements
- Located in the periodic table after uranium, these elements are not found naturally on Earth.
- Synthesized through nuclear reactions where nuclear particles collide, leading to the creation of heavier elements.
Reactivity
- Defined as the ease and speed with which an element interacts with other elements and compounds, influencing chemical behaviors.
