Science as a whole is the study of objects, environments and various natural events, and their effects are based on experiments and observations. It encompasses a systematic and logical approach towards the behaviour of changes around us and the events concerned with them. The curiosity of the human brain for understanding the world and things that are beyond this world has led to the development of various laws and principles.

Chemistry is one of science's fundamental branches concerned with the properties, structure, and constituents of matter or material and their interactions with other forms of matter. When you compare basic chemistry and modern chemistry, there is a lot of difference that can be seen.
Basic Chemistry originated in ancient times at the hands of famous scientists called Alchemists. It explained all the basics of the subject which were concluded after a series of experiments which shed light on how they really worked. Whereas Modern Chemistry prevailed in the 17th century which laid systematic steps in gaining knowledge about the matter. Modern chemistry brought about various theories which finally became justified with the experiments they conducted to prove how matter interacts.
The field of chemistry is the study of matter composition, structure, and properties. Chemistry is focused on the basic components of matter, atoms and molecules. Chemistry has provided answers to various questions. The quantitative measurement of the number of basic constituents of matter i.e. atoms and molecules and their dependence on the mass of the given matter is well explained by chemistry. Advances in chemistry have helped scientists and engineers to harness the energy associated with these atoms & molecules.
Today we can preserve food items for long periods of time; we have millions of chemicals that are used to manufacture a variety of products in different industries. Cell phone covers, plastic bags, construction steel, pasteurized milk, photosynthesis, crackers that we burn, etc. are just a few examples of chemicals goods. These products are such deeply rooted in our lives that we fail to visualize their importance and the role of the science behind them.
