A chemical bond is a lasting attraction between atoms that enables the formation of chemical compounds. This bond occurs when atoms share or transfer electrons, leading to stable arrangements. The main types of chemical bonds are covalent bonds, where atoms share electrons, and ionic bonds, where electrons are transferred from one atom to another. Chemical bonds are essential for creating the diverse range of substances found in nature. They determine the properties of materials, such as solubility, melting points, and conductivity. Understanding chemical bonds is fundamental in fields like chemistry, biochemistry, and materials science.
