Atom - The basic unit of matter, consisting of a nucleus (protons and neutrons) surrounded by electrons.
Element - A substance made up of only one type of atom. Example: Oxygen (O)
Proton - A subatomic particle with a positive charge found in the nucleus of an atom.
Neutron - A subatomic particle with no charge found in the nucleus of an atom.
Electron - A subatomic particle with a negative charge found orbiting the nucleus of an atom.
Molecule - A group of atoms bonded together. Example: Water (H2O)
Molecular Compound - A compound made up of molecules. Example: Carbon Dioxide (CO2)
Ionic Compound - A compound made up of ions. Example: Sodium Chloride (NaCl)
Chemical - A substance made up of a mixture of atoms, ions, and molecules.
Mechanical mixture - A mixture of two or more substances that are not chemically combined. Example: Trail Mix
Solution - A homogeneous mixture of two or more substances. Example: Saltwater
Suspension - A heterogeneous mixture where the particles settle out over time. Example: Sand and Water
Period - A row of elements in the periodic table.
Pure Substance - A substance made up of only one type of atom or molecule. Example: Gold (Au)
Examples:
- Atom: Carbon (C)
- Element: Iron (Fe)
- Proton: Hydrogen (H)
- Electron: Helium (He)
- Molecule: Methane (CH4)
- Molecular Compound: Sugar (C12H22O11)
- Ionic Compound: Calcium Carbonate (CaCO3)
- Chemical: Gasoline
- Mechanical mixture: Sand and Gravel
- Solution: Vinegar and Oil Dressing
- Suspension: Muddy Water
- Period: The third period of the periodic table
- Pure Substance: Water (H2O)
