2. Chemistry • A particular element or an atom of an element is depicted by a chemical symbol. • The method by which an atom or radical combine with other chemical species easily is represented by its valency. • A group of atoms which behaves like a single unit and shows valency is known as radical. • The process of transformation of one set of • chemical substances to another is called a chemical reaction. • A chemical equation expresses a chemical reaction by representing the reactants, products and their physical states symbolically. • Analytical chemistry uses qualitative and quantitative observation to identify and measure the physical and chemical properties of substances. In a sense, all chemistry is analytical. • Physical chemistry combines chemistry with physics. Physical chemists study how matter and energy interact. Thermodynamics and quantum mechanics are two of the important branches of physical chemistry. • Organic chemistry specifically studies compounds that contain the element carbon. Carbon has many unique properties that allow it to form complex chemical bonds and very large molecules
