The Map of Chemistry

The Basics of Chemistry

This section provides an introduction to the subject of chemistry, explaining the composition of the universe and the importance of chemistry in various aspects of human civilization.

The Composition of Matter

  • The universe is primarily made up of matter, with 98% being hydrogen and helium. These elements were formed through fusion in supergiant stars billions of years ago.
  • Chemistry studies the different forms and interactions of matter, ranging from simple atoms to complex biological molecules like proteins and DNA.

Historical Significance

  • Humans have had a long-standing interest in chemistry, as it played a crucial role in our development. Fire, for example, was a chemical reaction that led to advancements such as cooking food and metalworking.
  • Many advances in human civilization have been built upon chemical discoveries, including metalworking, manufacturing fertilizers, creating new materials, and developing drugs.

Elements and Atoms

  • Atoms are the smallest units of matter. The periodic table organizes different types of atoms called chemical elements.
  • Elements within each column share similar chemical properties. Atoms consist of protons and neutrons in the nucleus surrounded by electrons that determine their behavior.

Molecules and Compounds

  • By combining atoms, molecules are formed. Different types of molecules are known as chemical compounds.
  • Chemical compounds often exhibit distinct properties compared to their constituent elements. For example, hydrogen is explosive while oxygen supports combustion, but when combined into water (H2O), they create a non-explosive substance.

Mixtures and Bonding

  • Substances can exist as mixtures where multiple substances coexist without chemically bonding together.
  • Atoms bond together through various mechanisms such as sharing or transferring electrons to achieve lower energy states.

Energy and Reactions

  • Understanding how energy moves within chemical substances is vital for predicting reactions.
  • Energy determines the state of matter (solid, liquid, or gas) and influences reaction rates. Catalysts can increase reaction rates by providing a more energetically favorable environment.

Chemical Laws and Reactions

  • Chemical reactions involve compounds reacting with each other, resulting in products. These reactions are governed by chemical laws.
  • The conservation of mass and energy is a fundamental principle in chemistry, stating that no matter or energy is created or destroyed during a chemical reaction.
  • Kinetics studies the speed of reactions and factors influencing reaction rates.
  • Oxidation-reduction (redox) reactions involve the transfer of electrons between reactants. Acids and bases play important roles in chemical reactions.

Equilibrium and Phases

  • Equilibrium occurs when the amounts of substances involved in a reaction remain constant, even though the reaction may still be occurring.
  • Phase changes, such as solid to liquid or liquid to gas, also involve equilibrium.
  • pH indicates whether a substance is an acid or base based on its ability to donate or accept hydrogen ions.

These notes provide an overview of the basics of chemistry, including the composition of matter, historical significance, elements and atoms, molecules and compounds, mixtures and bonding, energy and reactions, chemical laws and reactions, equilibrium and phases.

Video description

The entire field of chemistry summarised in 12mins from simple atoms to the molecules that keep you alive. #chemistry #DomainOfScience If you would like to buy a poster of this map, they are available here: https://www.redbubble.com/people/dominicwalliman/works/26426671-the-map-of-chemistry I have also made a version available for educational use which you can find here: https://flic.kr/p/UBS4mf and a widescreen version: https://flic.kr/p/UNA1LW Errata and notes: 1. I got the Oxidising Agent and the Reducing Agent the wrong way around! Sodium is the Reducing agent and Chlorine is the Oxidising agent. My confusion was that when a sodium atom looses an electron it becomes oxidised, so in my simple brain, I called it the oxidising agent. That is wrong because the agent that oxidises the sodium is the chlorine atom and so the labels are the wrong way around. Doh! 2. I drew the hydrogen H2 molecule with a double bond but it should be a single bond because they are bonded with a single covalent bond. 3. Where I have drawn carbon dioxide, the carbon should have a double bond to each of the oxygens. 4. Apparently Feynman diagrams are not that useful for theoretical chemistry, so perhaps that wasn't the best choice for the illustration. The feedback in the comments from a real theoretical chemist is "All we deal with is shuffling around electrons, but many many many electrons, so a Feynman diagram would need to be huge but at the same time would be very very repetitive." 5. In analytical chemistry, I should have called it distillation rather than precipitation. 6. My definition of organic chemistry being about ‘life’ is not very good. I should have said that organic chemistry looks at compounds that contain carbon. But there are some compounds in inorganic chemistry that also contain carbon, like carbon dioxide so I guess I'd also have to state that inorganic chemistry is almost everything else. 7. I said that fuels are inorganic chemistry which is misleading when I drew a car next to it. My understanding is that there are inorganic fuels that don't contain carbon, but obviously all the fuels we are familiar with are organic. I thought a picture of a car would tie a few things together elegantly, but it ended up giving the wrong impression. That’s okay, I’m still learning! :D 8. In inorganic chemistry, I should have stated that all natural minerals fall under inorganic chemistry so as not to be misleading, otherwise you might go way thinking that only man-made substances fall under inorganic chemistry which is not true. I said that 'a lot of the inorganic compounds that are studied are man-made' meaning that the cutting edge of research is mostly man-made substances. 9. Apparently water is not the most inflammable substance. I thought it was so that is interesting. 10. In the bonding section, hydrogen bonding and van der waals forces are technically inter molecular forces.
