Fundamentals of Chemistry
The vocabulary everything else is built on: elements, compounds, mixtures and the mole.
What this lesson covers
Fundamentals of Chemistry is a 9-part Class 9 Chemistry lesson. Each part makes one point and then hands over to the next, so it can be read in a sitting or picked up again at the part you stopped on. It defines the idea in plain words before using it, works through an example step by step, shows where it is used outside the textbook, names the mistakes that cost marks in an exam, ends with a recap of what to remember.
How it begins
Chemistry is the study of matter. What it is made of, how it behaves, and how it changes into something else. Everything you can touch is matter: it has mass and takes up space. Chemistry sorts all of it into three categories, and telling them apart is the first skill to master. Element: one kind of atom only. Cannot be broken down chemically. Oxygen, iron, carbon.
