If you are looking for chemistry basics for beginners, this page is the starting point. The articles on this site are grouped into three categories: Fundamentals, Green Chemistry, and Energy Storage. Each category has a short description and a reading order, so you can see where to begin and what comes next.
What this site helps you understand about chemistry
Chemistry explains why ice floats, why lemon juice tastes sour, and why a battery can hold power. This site covers the ideas behind those everyday facts, written for people with little or no chemistry background. It also follows those ideas toward sustainability and clean energy.
For a look at how chemistry shows up in ordinary life, read Chemistry in Daily Life. To see what the site is for, visit the About Us page.
Fundamentals: start with atoms, bonds, and reactions
This category covers the building blocks. Everything later on the site depends on knowing what atoms are, how they join, and how those joins change. Read these in order:
- Atoms And Molecules, the first article for anyone new to chemistry
- Molecular Structure, on how atoms arrange themselves into different substances
- Chemical Bonding, on how atoms stick together to form molecules
- Chemical Reactions, on breaking and making bonds
Once you understand bonds, reactions are easier to follow: a reaction is a rearrangement of bonds.
How matter behaves: solids, liquids, gases, and phase changes
The next part of Fundamentals moves from single molecules to large groups of them. Start with Kinetic Molecular Theory, which describes how particles move. The three articles that follow apply it to each state of matter:
After those, read Phase Transitions to see how matter moves between solid, liquid, and gas. Supercritical Fluids follows, covering the conditions where the line between gas and liquid disappears.
Phase transitions matter beyond this section, because the Energy Storage category builds directly on them.
Acids, bases, and buffers: chemistry that keeps things in balance
This section covers a group of ideas that appear in food, cleaning products, and the human body. Start with Acids and Bases for the basic terms. Then read Buffer Systems, which explains how a solution resists changes in acidity.
The last article applies the idea to a living system. Buffer Systems in Living Organisms looks at the bicarbonate buffer in blood.
Green Chemistry: making chemistry safer and more sustainable
Green chemistry asks how to design chemical products and processes that are safer and produce less harm. You need the Fundamentals first, mainly bonds and reactions. After that, read in this order:
- Green Chemistry Principles, the overview
- Breaking Down the Green Chemistry Principles, a closer look at the principles one at a time
- Sustainable Chemistry, on innovation toward a greener future
- Biodegradable Materials, on materials designed to break down
- Renewable Energy and Biodegradable Materials, which connects these topics under the heading of sustainability
Energy Storage: phase change materials and the chemistry of clean power
This category ties the earlier ideas to energy. Start with Renewable Energy: The Chemistry Behind Clean Power, which sets out the chemistry of clean energy sources.
Then move to Phase Change Materials. These are substances that store and release energy as they change phase, so the Phase Transitions article from Fundamentals helps here. The category ends with PCM-Based Technologies, on how this chemistry is applied in daily life and work.
Not sure where to begin? Pick a path by what you’re curious about
Choose the line that sounds most like you:
- “I have never studied chemistry.” Begin with Fundamentals and read the articles in the order listed.
- “I want to understand sustainability.” Read Atoms And Molecules and Chemical Reactions first, then go to Green Chemistry.
- “I care about clean power.” Read Phase Transitions in Fundamentals, then go straight to Energy Storage.
- “I am curious about the body.” Read the Acids, bases, and buffers section, which ends with blood chemistry.
You do not need to finish a whole category before moving on. The order inside each one is a suggestion, and each article is written to be understood by a beginner.
Pick one category and open its first article: start with Atoms And Molecules if chemistry is new to you.
