istry
Early humans utilized fire, paint, and metal and studies its properties in order to build tools and survive during Ancient times. When civilization sprouted, humans began to wonder about the composition behind the everyday materials we see, and the theories behind them.
​
Back then, humans did not have advanced tools or the scientific knowledge required to accurately understand the world, but a lot of theories were made in order to expand their understanding. The Greek Philosopher Democritus gave rise to the idea of atomism, the idea in which all matter are made of small, indestructible particles named "atomos" at around 380 BC. However, the more popular philosophers Plato and Aristotle adopted the idea of classical elements, where all matter was made of fire, air, water, and earth, which was not debunked until the atom was proven to exist.
​
For an extended period of time, Europe did not advance much in the sciences as they believed in existing ideas and belief systems, especially in the realm of Christianity. The scientific revolution only began in the 16th and 17th Centuries, an event that pushed Europe into acknowledging or advancing their scientific understanding. However, despite this, a lot of scientific concepts such as heliocentrism, the concept which the Earth revolves around the Sun, received backlash from the Church as it opposed their concept in which Earth was the centre of the universe.
​
However, as time passed, Europe became a haven for scientific studies. John Dalton's atomic theory gave rise to the present-day chemistry concepts we have today by introducing the theory of atoms, derived from "atomos" into the scientific field. Later, Thomson's, Rutherford's, Bohr's, and more scientists' models also significantly contributed to the study of chemistry. Mendeleev developed the periodic table in 1869 and created patterns, atomic families, and predictions for undiscovered atoms through an table organized by the atoms' weight.
​
In the present, chemistry is used in various advancements in all sorts of fields, including engineering, mechanics, agriculture, medicine, and much more. Chemistry has also been split into
specific subcategories, such as organic chemistry and nuclear chemistry.

Khan Academy
​
Khan Academy has already been featured in the Math subject page, but it also teaches chemistry very throughly and in a way that's extremely easy to understand! Not only does it have videos to teach you about the concept, it also has quizzes and articles that will help you hone your skills and improve your overall capabilities.
​
The Chemistry content covers all content primarily needed in high school, divided into various sections. Since they are not ordered by grade, I recommend you to check which sections are the ones you are going to be quizzed on or learning before you start doing the units.
​
Chemquiz.net​
Chemquiz.net contains a large variety of quizzes which you can customize to facilitate your learning and review for quizzes and exams. There are currently 41 different quizzes available that covers a large range of topics, so you can search for the topics you need to review anytime.
​
Personally, I really enjoy the balancing equations quiz as you could customize the difficulty, amount of questions, reaction types, and quiz format. It is an extremely useful tool to generate quizzes and it also has a built-in grading system.

å…ƒç´ æ¥½ç« (lit. Elements Symphony)​
This is mostly here because I personally like it, but å…ƒç´ æ¥½ç« is a really amazing series that features humanized elements of the periodic table and has a published book that teaches chemistry in a fun and lighthearted way. The book features course content in Japanese high schools, and the author has even been featured on television in a chemistry series.
​
However, the series is mostly in Japanese, but hopefully it might get translated soon!

Totally not Nikola Tesla, Erwin Schrödinger, and Albert Einstein
