It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during reactions with other substances. [2][3][4][5] Chemistry also addresses the nature of chemical bonds in ...

2024年11月22日 · 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.

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.

chemistry, Science that deals with the properties, composition, and structure of substances (element s and compound s), the reactions and transformations they undergo, and the energy released or absorbed during those processes.

2019年10月3日 · Learn how chemistry, the study of matter and energy and how they interact, find out what chemists do, and discover why it's an important subject to study.

Chemistry is a branch of natural science that deals principally with the properties of substances, the changes they undergo, and the natural laws that describe these changes. The study of chemistry spans the range from qualitative in focus to quantitative.

Chemistry is the study of matter, analysing its structure, properties and behaviour to see what happens when they change in chemical reactions. As such, it can be considered a branch of...
