It depends on the substance your are talking about. It could be a compound, mixture, or substance; depending on the substance. If it is an element off the Periodic Table, it is an element. If it is two elements chemmically combined, it is a compound. If it is two elements that are not chemically combined, it is a mixture.
An element is the name of the substance.
If the atoms have bound to other atoms, it is a compound.
if a substance is made from one compound or element, then surely they are pure?
Because some are made up of a single element, while others contain a combination of different elements.
a pure substance
to combine two elements to form a new substance EX:salt,milk
You must define the word dirt. To some it is a mark on clothing, to some the soil or to others something an animal leaves behind. If you mean soil, no, it is not pure. Soil is made of grains of various minerals with added plant matter and a liberal dose of bacteria.
a refrigerant that does not change its pressure/temperature relationship when changing phases. CFC are pure compound refrigerants.

Different elements all have very different properties. However, you can define an element as a substance with only one type of atom in (e.g. only sulphur atoms). If a substance has more than one type of atom in, then it is either a compound or a mixture, depending on whether the elements have bonded.

How would you define a subtancebased on what you have obsrved
No. Define element - a single type of atom.
No elements are found within other elements, which is how we define an element; As a substance consisting of one type of atom.

mixture strength
1_A homogeneous ( same throughout) substance formed when one substance (called a salute) dissolves into another ( known as the solvent). 2_Solution is a mixture in which its components are evenly mixed. A solution is formed when one or more solutes dissolve in a solvent.
