CHEMICAL COMBINATION
Chemical combination refers to the process by which two or more elements or compounds unite to form new substances with distinct properties. This phenomenon is governed by fundamental laws such as the Law of Conservation of Mass, which states that mass is neither created nor destroyed during a chemical reaction, and the Law of Definite Proportions, which asserts that a given compound always contains its constituent elements in fixed ratios by mass. Chemical combinations can occur through ionic bonding, covalent bonding, or metallic bonding, depending on how atoms share or transfer electrons to achieve stability. Understanding chemical combination is essential for comprehending the formation and behavior of the vast array of substances found in nature and synthesized in laboratories.
