Study Notes
Elements Classification
- Elements are classified into three categories: metals, nonmetals, and metalloids, each with unique properties.
Metals
- Typically solid at room temperature.
- Known for malleability, allowing them to be hammered into thin sheets.
- Exhibit ductility, enabling them to be stretched into wires.
- Possess a shiny, reflective luster.
- Excellent conductors of heat and electricity, useful in various applications.
Nonmetals
- Can exist in solid, liquid, or gaseous states.
- Usually have dull, non-reflective surfaces.
- Characterized as brittle, breaking easily instead of bending.
- Poor conductors of heat and electricity.
- Some nonmetals, like noble gases, exhibit non-reactivity.
Metalloids
- Solid at room temperature, displaying properties of both metals and nonmetals.
- Can have either shiny or dull appearances.
- Generally brittle, similar to nonmetals.
- Function as semiconductors, conducting electricity better than nonmetals but not as efficiently as metals, making them important in electronics.
