Explore chemistry concepts with free lessons and practice on Khan Academy, covering topics from atoms to chemical reactions.
Chemistry forms the fundamental basis for biology and medicine. From the structure of proteins and nucleic acids, to the design, synthesis and manufacture of drugs, chemistry allows you. Chemistry is the branch of science dealing with the structure, composition, properties, and the reactive characteristics of matter.
You can teach yourself general chemistry with this step-by-step introduction to the basic concepts. Learn about elements, states of matter, and more.
At the heart of chemistry are substances — elements or compounds— which have adefinite composition which is expressed by a chemical formula. In this unit you will learn how to write and interpret chemical formulas both in terms of moles and masses, and to go in the reverse direction, in which we use experimental information about the ...

Chemistry, the science of the properties, composition, and structure of substances (defined as elements and compounds), the transformations they undergo, and the energy that is released or absorbed during these processes.
Chemistry is the study of matter—what it consists of, what its properties are, and how it changes. Being able to describe the ingredients in a cake and how they change when the cake is baked is called chemistry. Matter is anything that has mass and takes up space—that is, anything that is physically real.
Introductory Chemistry is intended for a one-semester introductory or preparatory chemistry course. Throughout the chapters, David presents two features that reinforce the theme of the textbook, that chemistry is everywhere. The first is the boxed feature titled, appropriately, ”Chemistry is Everywhere“.
Chemistry Definition - Chemistry is the study of matter, its properties, how and why substances combine or separate to form other substances, and how substances interact with energy. Learn about Chemistry, its branches, and the key concepts covered under the subject at the K-12 level.
