Elements,Mixtures, and Compounds:
- consists of atoms of two or more different elements bound together,
- can be broken down into a simpler type of matter (elements) by chemical means (but not by physical means),
- has properties that are different from its component elements, and
- always contains the same ratio of its component atoms.
- consists of only one kind of atom,
- cannot be broken down into a simpler type of matter by either physical or chemical means and can exist as either atoms (e.g. argon) or molecules (e.g., nitrogen).
- consists of two or more different elements and/or compounds physically intermingled,
- can be separated into its components by physical means, and
- often retains many of the properties of its components. By-BREN F.
