According to Roald Hoffman chemistry is not only the science of 100 elements but diversity of infinite varieties of molecules which are prepared from them. This purpose can be understood and described by the fundamental particles that are atoms and molecules of matter. Is it possible to observe these particles or can they be compared? Can we count the number of atoms or molecules in a definite quantity of matter?

Can a quantitative relationship be established by the number of atoms or molecules in definite quantity of matter? Science is a bridge to understand the nature. In other words, science is a continuous human effort to understand nature using systemic knowledge. The study of chemistry is so wide and diversified, that it is classified in various disciplines such as inorganic, organic, physical, analytical industrial, biochemistry etc.

Chemistry is science of occurrence and synthetic composition, structure and properties of substance. The branches of science like chemistry, physics, biology, geology are interrelated to one another. Chemistry plays an important role in our everyday life. Please forward this error screen to 216.
