Matter classification
Anmerkungen:
- All matter is made up by particles that can be protons, neutrons, electrons, atoms, ions ( charged atoms ) and molecules.
These particles are attached to others very tightly ( solids ), not that much ( liquids ) and far appart ( gases ).
- ACCORDING TO THE STATE
- SOLID
Anmerkungen:
- Particles in solids are tightly packed. SOLIDS then have DEFINITE volume and shape
- LIQUID
Anmerkungen:
- Particles in liquids are farther appart if compared to SOLIDS, because of this liquids flow and tend to occupy the SHAPE of their container, but keep their volume.
- GAS
Anmerkungen:
- The particles in a gas are far away, they are not attracted among them and move freely.
GASES tend to occupy all available space and this makes them have VARIABLE volume and shape.
- ACCORDING TO PROPERTIES
- PURE SUBSTANCES
- Elements
Anmerkungen:
- Made up by the SAME kind of atoms.
- Compounds
Anmerkungen:
- Made up by two or more atoms of DIFFERENT elements combined at FIXED ( DEFINITE ) proportions.
- MIXTURES
- Homogeneous
- Heterogeneous
