Atoms and Basic Chemistry Concepts
Everything you touch is made of atoms - they're literally the building blocks of the universe. An element contains only one type of atom (like pure oxygen or magnesium), whilst a compound has different atoms chemically bonded together (like water, which is hydrogen and oxygen stuck together).
Mixtures are completely different because the substances aren't chemically bonded - think of air, which is just different gases floating about together. You can separate mixtures using various techniques, but compounds need chemical reactions to break apart.
Matter exists in three main states - solid, liquid, and gas. In solids, particles vibrate in fixed positions like people in assigned cinema seats. Liquids let particles move past each other freely, whilst gases have particles zooming around randomly at high speeds with loads of space between them.
Remember: You need energy (heat) to overcome the forces holding particles together when melting or evaporating substances!
The history of atomic structure is like a detective story. John Dalton started it all, then JJ Thompson proposed the "plum pudding model." Ernest Rutherford discovered the tiny, positively charged nucleus by firing particles at gold foil, and Niels Bohr worked out that electrons exist in energy levels around the nucleus.

Atomic Structure and the Periodic Table
Protons have a +1 charge and mass of 1, neutrons are neutral with mass 1, and electrons have a -1 charge but virtually no mass. Think of the atom like a football stadium - the nucleus is a marble in the centre, and electrons orbit around the outside.
The atomic number tells you how many protons an element has (carbon always has 6). The mass number is protons plus neutrons added together. For an atom to be neutral, it needs equal numbers of protons and electrons - if not, it becomes an ion.
Isotopes are like twins with different weights - same element, but different numbers of neutrons. Some relative atomic masses aren't whole numbers because they're averages of all the isotopes that exist naturally.
Top tip: The periodic table is arranged by atomic number, not mass - Dmitri Mendeleev figured this out!
Metals always donate electrons to get empty outer shells, forming positive ions (like Na+). Non-metals accept electrons to get full outer shells, forming negative ions or sharing electrons instead.

Groups in the Periodic Table and Chemical Bonding
Group 1 metals (alkali metals) get more reactive as you go down because their outer electron is further from the nucleus, making it easier to lose. They all form +1 ions and react vigorously with water.
Group 7 elements (halogens) do the opposite - they get less reactive going down the group but their boiling points increase. They form -1 ions by accepting one electron. Group 0 (noble gases) are practically unreactive because they already have full outer shells.
Metallic bonding creates a lattice of metal ions surrounded by a "sea" of delocalised electrons. Since electrons can move freely, metals conduct electricity and heat brilliantly - that's why your radiators are metal!
Key concept: In ionic bonding, metals donate electrons to non-metals, creating oppositely charged ions that attract each other strongly.
Ionic compounds have high melting points because you need loads of energy to break those strong ionic bonds. The charges in any ionic compound must always add up to zero - it's like balancing a equation!
4
of 8
Covalent Bonding and Giant Structures
Covalent bonding happens when non-metals share electrons to get full outer shells - it's like sharing your lunch so you both get fed! Every covalent bond consists of a pair of shared electrons, and you can show this using dot and cross diagrams.
Simple covalent substances have low boiling points because you only need to break weak forces between molecules, not the actual covalent bonds. Think of it like unsticking Post-it notes rather than tearing them in half.
Giant covalent structures are massive networks of atoms all bonded together - imagine a spider's web that goes on forever! These have very high melting points because you'd have to break actual covalent bonds.
Amazing fact: Diamond is one of the hardest substances known because of its incredibly strong covalent bonds in all directions!
Graphite can conduct electricity because it has delocalised electrons, and its layers can slide past each other (that's why pencils work). Alloys are stronger than pure metals because different-sized atoms disrupt the regular structure, preventing layers from sliding easily.
5
of 8
Chemical Reactions and the Reactivity Series
Displacement reactions happen when a more reactive metal kicks out a less reactive one from a compound - it's like queue-jumping but for atoms! Most metals react with acids to produce a salt and hydrogen gas, whilst metal carbonates give you a salt, carbon dioxide, and water.
The reactivity series is like a league table for metals - the higher up, the more reactive. You can use this to predict which displacement reactions will happen and which won't.
Diamond is incredibly hard due to its strong bonds in all directions. Graphite has delocalised electrons forming weak bonds between layers, so it conducts electricity and the layers can slide (making it perfect for pencil lead).
Cool applications: Fullerenes and nanotubes are used in electronics, composites, and medical purposes because of their unique cage-like structures.
Understanding these structures helps explain why different forms of carbon have such different properties despite being made of exactly the same atoms!

of 8
Oxidation, Reduction, and Electrolysis
Remember "OILRIG" - Oxidation Is Loss, Reduction Is Gain (of electrons). Even when oxygen isn't involved, we still use these terms for any reaction where electrons are transferred between atoms or ions.
Neutralisation happens when acids (pH < 7) react with alkalis (pH > 7) to produce a salt and water . The pH scale runs from 1-14, and each step represents a 10× change in hydrogen ion concentration - that's a massive difference!
Electrolysis uses electrical current to force chemical reactions by attracting ions to oppositely charged electrodes. The positive anode and negative cathode cause oxidation and reduction respectively.
Important: Electrolysis only works when ions can move freely - so ionic compounds must be molten or dissolved in solution.
For molten compounds, you get the pure elements. With solutions, it's trickier because water interferes - halide ions are always oxidised at the anode, whilst hydrogen ions (being less reactive than most metals) are reduced at the cathode.
7
of 8
Electrolysis of Solutions Continued
When electrolyzing solutions, halide ions (F⁻, Cl⁻, Br⁻) are always oxidised at the anode. If there's no halide present, oxygen gets oxidised instead, producing oxygen gas. Meanwhile, H⁺ ions are usually reduced at the cathode because they're less reactive than most metal ions.
The more reactive metal ions stay dissolved in solution whilst the less reactive ones get reduced. This is why you can extract some metals but not others using electrolysis of solutions.
Exothermic reactions release energy and get hot because there's a net decrease in potential energy, which converts to kinetic energy (heat). Endothermic reactions absorb energy and get cold as kinetic energy converts to potential energy.
Practical tip: You can find the exact neutralisation point by reacting acid with increasing volumes of alkali and measuring maximum temperature - the peak shows perfect neutralisation!
Activation energy is like the initial push needed to get a reaction started - imagine pushing a boulder over a hill before it rolls down the other side.
8
of 8
Energy Changes and Bond Energies
The energy change in a reaction depends on the difference between energy needed to break bonds and energy released when forming new bonds. If more energy is released than used, the reaction is exothermic (gets hot). If more energy is needed than released, it's endothermic (gets cold).
You can calculate energy changes using bond energies - just add up all the energy needed to break reactant bonds, then subtract all the energy released making product bonds. A negative answer means exothermic, positive means endothermic.
Required practical work involves reacting acids with alkalis and measuring temperature changes. Plot a graph of temperature against volume of alkali added - the peak shows you the exact neutralisation point.
Exam tip: Always show your working clearly in bond energy calculations - even if you get the final answer wrong, you can still get marks for the correct method!
Understanding energy changes helps explain why some reactions happen spontaneously whilst others need constant heating. It's all about energy balance and whether the products are more or less stable than the reactants.
