What is matter? Matter: is anything that takes up space and posses rest mass, especially as distinct from energy.
Pure substances: are defined as substances that are made of only one type of atom or only one type molecule ( a group of atoms bonded together).
Example: Pure Substances include tin, sulfur, diamond, water, pure sugar (sucrose, table salt) (sodium chloride) and baking soda (sodium bicarbonate)
Element:each of more than one hundred substances that cannot be chemically interconverted or broken down into simpler substances and are primary constituents of matter. Example:Some of these names are familiar to us, such as nitrogen and sodium, and some are less familiar, such as dysprosium and roentgenium. Element 1 is hydrogen, element 2 is helium, element 3 is lithium, element 8 is oxygen etc.
Compound: Is a substance in which the atom of two or more elements are chemically combined. Example: There are many types of compound, like carbon dioxide (carbon and oxygen), common salt (sodium, chlorine), marble ( calcium, carbon, oxygen), copper (II) sulphate (copper, sulphur, oxygen) and hydrogen chloride (chlorine and hydrogen). Compound is made up of two or more elements. Examples include water.
Homogeneaus: consisting of parts all of the same kind. Example: Salty water — a mixture of salt and water.
Solution: a liquid mixture in which the minor component (the solute) is uniformly distributed within the major component (the solvent). Example: Some examples of solutions are salt water, rubbing alcohol, and sugar dissolved in water.
Heterogeneaus: A heterogeneous mixture is made of different substances that remain physically separate. Example: A good example of this is oil and water. When a solid and liquid are mixed together, it's called suspension.
Suspension: the system of springs and shock absorbers by which a vehicle is cushioned from road conditions
Colloids: Colloids include gels, sols, and emulsions; the particles do not settle and cannot be separated out by ordinary filtering or centrifuging like those in a suspension.
