Study Notes
Characteristics of Metals, Nonmetals, and Metalloids
- Metals exhibit luster, giving them a shiny appearance.
- Nonmetals tend to gain electrons during chemical reactions.
- Many nonmetals exist as gases at room temperature, highlighting their variability in physical states.
- Metalloids possess characteristics of both metals and nonmetals, making them versatile elements.
- Metals are malleable, allowing them to be shaped easily without breaking.
- Some metalloids function as semiconductors, bridging the gap between conductors and insulators.
- Metals are excellent conductors of heat and electricity due to their free-moving electrons.
- Nonmetals have tightly held valence electrons, resulting in different chemical properties compared to metals.
- With one exception (mercury), all metals are solid at room temperature, indicating their structural stability.
- Metals are also ductile, meaning they can be drawn into wires without breaking.
- Nonmetals are typically brittle, breaking or shattering easily under stress.
- Valence electrons in metals are held loosely, making them more reactive.
- Nonmetals generally tend to lose electrons when reacting, contrasting with nonmetals that typically gain them.
- Metalloids are good conductors of heat and electricity, but not to the extent of metals.
- Nonmetals serve as poor conductors of heat and electricity, limiting their utility in conductive applications.
- Nonmetals lack shine and are often described as not shiny in appearance compared to metals.
