# Unit 1: Chemistry
|
|
|
|
- Matter - has mass, takes up space.
|
|
- fundamental unit -> ATOMS
|
|
|
|
## Atoms
|
|
- Atoms are the smallest unit of an element that still retains its properties
|
|
- Atoms are made of subatomic particles
|
|
- Relative Charge: compared to something.
|
|
- AMU = atomic mass units
|
|
- models allow people to make accurate preictions about the behaviour of matter
|
|
- atmoic notation $`_{19}K`$
|
|
- an isotope is an atom (or atoms) of an element with a unique # of neutrons
