Chemistry is a branch of physical science that studies the composition, structure, properties, and changes in chemical materi.Ilmu covering topics such as the nature of atoms, how atoms form chemical bonds to produce chemical compounds, the interaction of substances through intermolecular force that produces general properties of matter, and the interaction between substances through chemical reactions to form different substances.

Chemistry (from Arabic: كيمياء, transliteration: Kimiya = change objects / substances or Greek: χημεία, transliteration: khemeia) is the study of the composition, structure and properties of substances or materials from the atomic scale to the molecule and change or transformation and their interactions to form materials that are found everyday. Chemistry also studied understanding the properties and interactions of individual atoms for the purpose of applying that knowledge at the macroscopic level. According to modern chemistry, physical properties are generally determined by the structure of matter at the atomic level, which in turn is determined by the style antaratom and chemical bonding.
