Study Notes
Classifying Elements: Metals and Non-Metals
- Elements are classified as metals or non-metals based on unique properties.
- This classification helps understand how they interact and are used.
Properties of Metals
- Shiny appearance
- Excellent conductors of heat and electricity
- Malleable (can be hammered into shapes)
- Ductile (can be drawn into wires)
- Essential in construction, technology, and transportation
- Examples: Iron, steel (buildings, bridges, vehicles), copper (electrical wiring), aluminum (aircraft, packaging), gold, silver (jewelry, electronics)
- Extracted from ores through mining and refining.
- Overuse and extraction can cause environmental issues. Recycling and sustainable alternatives are important.
Properties of Non-Metals
- Generally poor conductors of heat and electricity
- Lack the luster of metals
- Can exist in solid, liquid, or gaseous states
- Diverse applications
- Examples: -Carbon (organic life, steel production, pencils) -Oxygen (respiration, combustion) -Silicon (semiconductors, computers, smartphones) -Nitrogen (fertilizers, agriculture)
- Reactivity or scarcity can limit their use.
Interrelation and Importance
- Metals and non-metals work together to drive human progress.
- Their complementary properties allow diverse applications (building, machines, sustaining life, advancing technology).
- Understanding these differences and uses is important for both chemistry knowledge and sustainable resource management.
