Study Notes
Chemistry is one of the oldest sciences, dating back thousands of years when early humans were attempting to explain and manipulate their environment through experimentation. It has evolved significantly over time into what we know today as a systematic study of matter, its properties, interactions with energy, changes in states, and chemical reactions between atoms and molecules. Understanding chemistry helps us understand how our bodies function, why the world around us looks and smells the way it does, and even how modern technology works.
Chemistry can broadly be divided into the following areas:
-
Inorganic Chemistry deals with elements other than carbon and their compounds. These are materials such as metals, minerals, rocks, soils, and water. They do not contain any hydrogen or have very low percentages of hydrogen present. Key concepts here include stoichiometry, thermodynamics, kinetics, and equilibrium.
-
Organic Chemistry focuses on the structure, properties, and reactions of organic compounds, which are those containing carbon and often derived from living organisms. This field includes polymer science, biochemistry, pharmacology, toxicology, and environmental chemistry.
-
Physical Chemistry studies the physical basis underlying the behavior of chemical systems. Topics covered range from classical mechanics and quantum mechanics to statistical thermodynamics and electromagnetism. Examples include phase transitions, spectroscopy, and photochemistry.
-
Analytical Chemistry involves qualitative and quantitative composition analysis of matter, especially by separation methods and instrumental techniques. Some common analytical instruments used are mass spectrometers, chromatographs, spectrometers, and electroanalysers.
In the past few decades, there has been increasing interest in interdisciplinary fields where chemists interact closely with specialists in other scientific disciplines like physics, engineering, geography, computer science, life sciences, sports medicine, agriculture, etc., to tackle both fundamental questions related to human wellbeing and societal needs. For instance, nanotechnology and green technologies aim to develop new applications and solve global problems using chemistry in innovative ways.
The International Year of Chemistry was declared for the year 2011 by the United Nations Educational Scientific and Cultural Organization (UNESCO) to celebrate the achievements of chemistry and its role in addressing global challenges. Through this initiative, chemists worldwide aimed to raise public awareness about chemistry's relevance to everyday life.
If you're interested in learning more about chemistry, consider exploring online resources and courses offered by universities and institutions, many of which are now available free of charge, along with podcasts, videos, textbooks, simulations, and games. There are also numerous national and international organizations dedicated to promoting the history, education, and application of chemistry, including the American Chemical Society and UNESCO.
