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)
