Chemistry is the science of matter and its transformations, and there are many important terms that have shaped this field. Terms like 'atom,' 'molecule,' and 'catalyst' are fundamental to understanding how substances interact with each other. Atoms, the smallest unit of matter, combine to form molecules, which are the building blocks of all substances.
In chemistry, catalysts are substances that speed up chemical reactions without being consumed in the process. These terms are essential for understanding everything from basic chemistry experiments to advanced industrial processes. Chemistry is also the key to creating new materials, medicines, and sustainable energy solutions.
