Important Chemical Compounds and Their Formulas

Explore Chemistry Compounds

Explore chemistry through simple, interactive lessons covering chemical formulas, compound names, molecular structures, elements, and their everyday uses.

Each compound is presented as a focused lesson so you can learn what its chemical formula means, which elements it contains, and how those atoms are arranged in the molecule.

What to expect in each compound lesson

• Chemical formula — identify the formula and understand the elements and number of atoms it contains.
• Compound name — learn the common or familiar name associated with the formula.
• Molecular structure — view a visual representation of the molecule and its atomic arrangement.
• Interactive atoms — select atoms in supported molecule diagrams to explore their basic properties.
• Quick facts — see useful information such as element counts, total atoms, and the compound's chemical family where available.
• Simple explanations — understand the compound through concise, learner-friendly descriptions and examples.

Chemistry Formulas

Start with the chemical formula and learn how it represents the atoms that make up a compound. For example, a formula such as H₂O shows that a water molecule contains two hydrogen atoms and one oxygen atom.

The lessons are designed for learners at different levels, from students becoming familiar with chemical symbols and formulas to learners who want a quick reference for common compounds.
