Скачать или смотреть Introduction to Molecules in Chemistry

Molecules in chemistry are the smallest fundamental units of chemical compounds that can take part in a chemical reaction. They consist of two or more atoms bonded together through chemical bonds, which can be covalent (sharing of electron pairs between atoms) or ionic (transfer of electrons from one atom to another). The structure, composition, and arrangement of atoms within a molecule determine its chemical properties and behavior in reactions. Molecules can vary greatly in complexity, from simple diatomic molecules like oxygen (O2) to large biomolecules like proteins and DNA. Understanding molecules is crucial for exploring the principles of chemical reactions, properties of substances, and the synthesis of new materials.
