Here is the basics
- An atom is a particle not chemically bonded with other atoms
- A molecule is a cluster of elements chemically bonded togeather
- An element is a single type of matter
- Compound is multiple types of element chemically bonded togeather
- Mixture is a mix of elements that is not chemically bond.
Difference between compound and mixture
COMPOUND
> chemically bonded by elements
> separated chemically (exp. heating, electricity ...)
> cannot be separated physically
whereas mixture
> not chemically bonded by elements
> can be separated physically ( exp. magnet, filtration ....)
> cannot be separated chemically
