With atomic-scale molecular

Chemistry (from the Arabic "transformation art" and the Greek khemeia. Alchemy is the study of the composition and properties of substances or materials on the scale of molecules and atoms to change or transformation as well as their interaction to form the material found everyday.

Chemistry is also studying the understanding of the nature and interactions of individual atoms in order to apply such knowledge on the macroscopic level. According to modern chemistry, physical properties are generally determined by the structure of matter at the atomic level, which in turn determined by the style antaratom.

macroscopic is the observation by using the eyes alone. This is because our eyes are also able to clearly see objects that size is not too big and not too small. Last is the microscopic observation. This observation is usually done using a tool called a microscope. The item is required because of large objects that we need to observe is too small and is unable to be viewed only by using the naked eye alone.

Chemistry is often referred to as the "central science" because it connects the various other sciences, like physics, material science, nanotechnology, biology, pharmacy, medicine, bioinformatics, and geology.
