Study Notes
Characteristics of Metals and Non-Metals
- Metals are typically good conductors of heat and electricity.
- Copper is an example of a metal that is a good conductor of heat and electricity.
Non-Metals
- Non-metals are poor conductors of heat and electricity.
- Iodine is an exception among non-metals, as it is lustrous.
- Carbon is unique among non-metals in that it is a solid at room temperature.
Reaction with Oxygen
- Metals react with oxygen to form basic oxides.
- Examples of metals that react slowly with air and form a protective layer that prevents corrosion include aluminum and zinc.
Acid-Base Reactions
- Metal oxides turn red litmus blue.
- Non-metals do not react with water or dilute acids.
Properties of Elements
- Non-metals do not exhibit the properties of metals.
- Oxygen and nitrogen are examples of non-metals.
- Carbon, sulfur, and phosphorus are also non-metals.
- Mercury is an exception among metals, as it is a liquid at room temperature.
- Osmium is a metal with the highest density among the mentioned elements.
