Chemistry is the science, which deals with the composition and properties of matter, changes in matter and the laws or the principles which govern these changes. Basically we study about different elements, matters and the chemical changes performed by applying different conditions on the reactions, resulting to for a new element, compounds.

Branches in Chemistry are as follows:

Agricultural Chemistry is the science of chemical compositions and changes involved in the production, protection, and use of crops and livestock.

Analytical chemistry determines the chemical composition of natural and artificial chemical compounds by chemical, physical and other techniques.

• Pharmacogenomics
• Pharmaceutical products

Practical chemistry

Biochemistry is a scientific branch that examines chemical substances, reactions and processes in living organisms.

Biological Chemistry is an interdisciplinary part of the natural sciences that studies the chemical processes in living organisms and examines the structure and function of cellular components, such as proteins, carbohydrates, lipids, nucleic acids, and other biomolecules.

Biotechnology is technology based on biology, especially when used in agriculture, food science, and medicine, Biotechnology is often used to refer to genetic engineering technology of the 21st century.

Chemical Biology is a interdisciplinary scientific branch between chemistry and biology with intent to examin biological systems with chemical techniques and tools.

Chemical engineering is the branch of engineering that deals with the application of physical science, with mathematics, to the process of converting raw materials or chemicals into more useful or valuable forms.

• Process engineering
• Technical chemistry

Combinatorial chemistry involves the rapid synthesis or the computer simulation of a large number of different but structurally related molecules

Combinatorial chemistry involves the rapid synthesis or the computer simulation of a large number of different but structurally related molecules

Astrochemistry and Cosmochemistry are the study of the chemical elements and chemical compounds, that can be found in the outerspace, in stars, planets, comets, meteorits, interstellar matter etc.

Environmental chemistry is a part of the natural sciences and examines the chemical and biochemical phenomena that occur in natural places.

The branch of chemistry that studies elementary (often very fast) chemical reactions as they occur; the experimental methods are often based on the use of femtosecond laser pulses.

As a branch of Applied Chemistry the food chemistry deals with the chemical examination and analysis of food and food components, and studies the chemical aspects of food technology.

Physical and Chemical Changes, Elements, Compounds and Mixtures.The Scientific Method Atoms, Models and Symbols The Periodic Table Molecules and Ions Naming Inorganic Componds Chemical Equations.

Information resources on geochemistry: factsheets, journals, databases, institutions, lecture notes etc.

Inorganic chemistry is the branch of chemistry concerned with the properties and behavior of chemicals compounds except organic compounds.

• Mineralogy
• Solid State Chemistry

Chemistry of plastics

Is the area of research engaged in the novel and nontrivial applications of mathematics to chemistry; it concerns itself principally with the mathematical modeling of chemical phenomena. Mathematical chemistry has also sometimes been called computer chemistry.

Mechanochemistry is the coupling of the mechanical and the chemical on a molecular scale includes mechanical breakage, polymer degradation under shear, cavitation-related phenomena (e.g., sonochemistry and sonoluminescence), shockwave chemistry and physics, and even the burgeoning field of molecular machines. It can be seen as an interface between chemistry and mechanical engineering.

is a branch of chemistry that involves aspects of biological, medical and pharmaceutical sciences. Medicinal Chemistry is concerned with the invention, discovery, design, identification and preparation of biologically active compounds, the study of their metabolism, the interpretation of their mode of action at the molecular level and the construction of structure-activity relationships.

The study of the synthesis and characterization of materials in the nanoscale size range (1 to 10 nanometers). These materials include large organic molecules, inorganic cluster compounds, and metallic or semiconductor particles.

The study of the carbon atom and the compounds it forms, mainly with the 20 lightest elements, especially hydrogen, oxygen and nitrogen. Some 3 million organic compounds have been identified and named.

Physical chemistry is a branch of chemistry dealing with the physical properties of chemical substances, and the application of physics to processes and phenomena in chemical systems.

• Electrochemistry
• Spectroscopy
• Physical Chemistry
• Thermodynamics

Soil chemistry is the interdisciplinary branch between soil sciences and chemistry and studies the chemical characteristics of soil.

Solid-state chemistry is the study of the synthesis, structure, chemical, and physical properties and the application of solid materials.

driving and accelerating chemical reactions through application of ultrasonic energy.

Spectroscopy - or: spectrometry - is the study of the interaction between matter and radiation.
