100 Chemical Formulae and Names of Compounds – A Complete Guide for Class 6 to 10 Students

Chemistry is the study of matter and the changes it undergoes. One of the most fundamental skills in chemistry is understanding chemical formulae and names of compounds. A chemical formula is a representation of a chemical substance using letters (symbols of elements) and numbers (subscripts) to show the number of each type of atom present in a compound . For students in Class 6 to 10, learning these basic chemical formulas is essential for mastering science and excelling in examinations. At Dhingra Classes Nashik, we believe that building a strong foundation in chemistry begins with understanding the language of chemical compounds.

In this article, we present a comprehensive list of 100 chemical formulae and names of compounds that are commonly used in daily life and frequently appear in school curricula.

📘 What is a Chemical Formula?

A chemical formula is a symbolic representation of a compound. It indicates the types of atoms present and the exact number of each atom in a molecule of the compound. For example:

  • Water (H₂O): Contains 2 hydrogen atoms and 1 oxygen atom.

  • Carbon Dioxide (CO₂): Contains 1 carbon atom and 2 oxygen atoms.

Formulae are derived using the valencies (combining capacities) of elements and are essential for writing balanced chemical equations.

📊 100 Chemical Compounds with Their Formulae and Names

Here is a comprehensive list of 100 chemical compounds, their chemical formulae, and common names where applicable. This list is organized into categories for easy reference.

📚 How to Memorize Chemical Formulae

TipDescription
Learn ValenciesUnderstanding the valency of elements is the key to writing formulae correctly. For example, sodium (Na) has valency 1, oxygen (O) has valency 2, so sodium oxide is Na₂O.
Use MnemonicsCreate memory aids to remember groups of compounds.
Group by FamiliesLearn acids, bases, salts, and organic compounds separately.
Practice RegularlyWrite formulae daily to reinforce memory.
Use FlashcardsWrite compound names on one side and formulae on the other.
