CGP GCSE Chemstry for AQA (Grade 9-1)---Topic 1-Atomic Structure and the Perodic Table
This is a mind map on the first topic in the CGP GCSE Chemstry Revision Guide, excluding the required praticles (sorry)
It follows the AQA spec and is for the new 9-1 grade system.
Hope you enjoy and learn something!!
NOTE: Most definitions are in the Bottom Right Corner, along with the Equations.
Sorry if the equations are hard to understand, i did the best I could.

- Atomic Structure and the Perodic Table
- Atoms
- They contain Protons,Neutrons and Electrons
- The atom is made up of the Nucleus and Shells
- The nucleus contains Protons and Neutrons, because of this it has a positive charge.
- The number of Protons are the same as the number of Electrons (except for ions)
- Its atomic number tells you how many Protons it has, the mass number tells you the total number of Protons and Electrons
- The number of Protons are the same as the number of Electrons (except for ions)
- Shells are where electrons are
- The nucleus contains Protons and Neutrons, because of this it has a positive charge.
- The atom is made up of the Nucleus and Shells
- They contain Protons,Neutrons and Electrons
- Elements
- Elements consist of atoms containing the same atomic number
- Atoms can be represented by symbols
- C=carbon,O=Oxygen,Na=Sodium
- Isotopes are the same element but have a different number of Neutrons
- Atoms can be represented by symbols
- Elements consist of atoms containing the same atomic number
- Compounds
- Atoms chemically join together to create compounds
- When compounds are formed Ions usually form (Ions will be in the Topic 2 mind map)
- Formulas show what atoms are in a compound
- When compounds are formed Ions usually form (Ions will be in the Topic 2 mind map)
- Atoms chemically join together to create compounds
- Chemical Equations
- Chemical changes are shown using chemical equations
- Symbol equations show atoms on both sides
- Symbol equations need to be balanced
- The main reason is because there must be the same number of atoms on both sides- Conservation of Mass
- Symbol equations need to be balanced
- Symbol equations show atoms on both sides
- Chemical changes are shown using chemical equations
- Mixtures and Chromatography
- Mixtures are easily seperated, unlike compounds
- The reason being that mixtures are not chemically bonded
- Paper Chromatography is a way of seperating inks from a single dot to see what colours are in certain inks
- Mixtures are easily seperated, unlike compounds
- History of the atom
- In 1897 J J Thomson created the plum pudding model
- In 1909 Rutherford fired alpha particles at a sheet of gold and proved the plum pudding model to be wrong
- Bohr created the Nuclear Model, which shows the nucleus and electrons in shells.
- About 20 years later James Chadwick found the Protons
- Bohr created the Nuclear Model, which shows the nucleus and electrons in shells.
- In 1909 Rutherford fired alpha particles at a sheet of gold and proved the plum pudding model to be wrong
- In 1897 J J Thomson created the plum pudding model

- Electronic Structure
- Electrons always occupy shells, the lowest shell is always filled first
- Only a certain number of electrons are allowed in each shell
- Atoms are happier when they have full electron shells
- In most atoms the outer shell is not full which makes the atom want to react
- 1st: 2, 2nd: 8 3rd: 8 4th: 2
- Atoms are happier when they have full electron shells
- Only a certain number of electrons are allowed in each shell
- Electrons always occupy shells, the lowest shell is always filled first
- Atoms
