Chemistry is the study of matter and energy, focusing on substances and their reactions. Chemists can work in labs, do fieldwork, or develop theories and models on computers. Many fields, including medicine and engineering, use chemistry to understand the world better.
General chemistry topics include things like atoms and molecules, how substances react, the periodic table, and the study of different compounds.

Students learn to describe the pattern in atomic number, atomic mass and atomic radius. Trends on the Periodic Table: Students learn to describe the pattern in atomic number, atomic mass, atomic ...
This lesson utilizes an adaptation of the board game Periodic: A Game of the Elements to help students better understand both general periodic trends and the law of conservation of energy. This ...
The periodic table isn’t just a list of elements—it’s a map of predictable patterns called periodic trends. These trends, like atomic radius, electronegativity, and ionization energy, help scientists ...
Learn about chemical reactions, elements, and the periodic table with these resources for students and teachers.
Welcome to the wide world of chemistry! This is an introduction to Chemistry 101 and an index of concepts and tools to help you learn chemistry.
Chemistry is the study of matter, its properties, and interactions with energy. Chemistry is related to other sciences like physics and biology and uses the scientific method. Studying chemistry helps us understand cooking, digestion, and even how medications work.
Chemistry studies how matter and energy interact, with atoms and molecules forming through chemical reactions. Chemistry is everywhere, as it involves everything you touch, taste, or smell in daily life. Chemistry is a hands-on and real-world science, providing tools to solve real problems and make new products.
