Everything around us is either a mixture, or a pure substance — and pure substances are either elements or compounds.
Understanding the Name of the Chapter
Nature
The basic make-up of a thing — what it is really made of.
Matter
Anything that has weight and takes up space.
Elements
The simplest substances that cannot be broken down further.
Compounds
Two or more elements joined chemically in a fixed ratio.
Mixtures
Substances simply mixed together, keeping their own properties.
What does the name of this chapter tell us?
- Matter is sorted by its "nature" — how it is built.
- Mixtures are just mixed; nothing new is made.
- Elements and compounds are the two pure types.
- A compound is a brand-new substance, not a mix.
