Study Notes
Metals Physical Properties
- Metals are malleable and ductile, meaning they can be shaped and molded without breaking.
- Metals are good conductors of heat and electricity, making them useful for various applications.
- Metals are lustrous (shiny) and can be polished to maintain their appearance.
- With the exception of mercury, metals are solids at room temperature.
- Metals are tough and strong, making them suitable for construction and other uses.
Metals Chemical Properties
- Metals have a high density, which contributes to their strength and durability.
- Metals form alloys with other metals or non-metals, allowing for the creation of new materials with unique properties.
- Some metals react with air and corrode, requiring protection to maintain their integrity.
- Metals are good conductors of heat and electricity, making them useful for various applications.
Non-Metals Physical Properties
- Non-metals are brittle (soft) and prone to breaking or shattering.
- Non-metals are poor conductors of heat and electricity, limiting their use in certain applications.
- Non-metals are non-lustrous (dull) and cannot be polished, with the exception of iodine.
- Non-metals can exist as solids, liquids, or gases at room temperature, depending on the specific element.
- Non-metals are neither tough nor strong, making them less suitable for construction and other uses.
Non-Metals Chemical Properties
- Non-metals are poor conductors of heat and electricity, unlike metals.
- Non-metals are not ductile or malleable, and do not form alloys with other metals or non-metals.
- Non-metals react more with metals compared to other non-metals.
- Non-metals usually react with other non-metals at high temperatures.
Oxides and Acids
- Metals react with Oxygen to form basic oxides.
- Non-metals react with Oxygen to form acidic or neutral oxides.
- Most metals displace Hydrogen from dilute acids.
- Non-metals do not react with dilute acids.
Chemical Reactions
- Substances that react are called reactants, and substances formed during a reaction are called products.
Types of Chemical Reactions
- There are six common types of chemical reactions.
- The 5 primary types of chemical reactions are: combination, decomposition, displacement, double displacement, and precipitation reactions.
Combination Reaction
- A type of chemical reaction where two or more substances combine to form a new substance.
Decomposition Reaction
- A type of chemical reaction where a single substance breaks down into two or more simpler substances.
Displacement Reaction
- A type of chemical reaction where one element displaces another element from a compound.
Double Displacement Reaction
- A type of chemical reaction where two compounds exchange partners, forming two new compounds.
- Example: BaCl2 + Na2SO4 → BaSO4 + 2NaCl
Precipitation Reaction
- A type of chemical reaction where a solid forms from a solution, usually as a result of mixing two solutions containing dissolved species.
- Precipitation reactions often involve the formation of an insoluble ionic compound when two solutions containing soluble compounds are mixed.
- Example: NaCl(aq) + AgNO3(aq) → AgCl(s) + NaNO3(aq)
