- Atoms, periodic table, compounds and elements
- Atoms
- Structure of an atom
- Charges: Protons = +1 neutrons = 0 Electrons=-1
- Overall most atoms have no electrical charge
- Electron Shell
- Electrons always occupy electron shell
- 1st shell = 2 electrons 2nd shell = 8 electrons 3rd shell = 8 electrons
- Most atoms don't have a full outer shell which makes them want to react to make a full outer shell
- Only noble gases have a full outer shell which makes them hard to react
- Elements
- All Elements are made up of only one type of atom
- Compunds
- compounds are made up of two or more types of atoms
- Periodic table
- The periodic table has groups and the amount of electrons on the outer shell depends on what group the atom is in E.g 8 or a full outer shell puts the atom in group 0, 3 electrons make the atom in group 3
- How the periodic table is spilt into metals and non-metals
- Atoms
