Transcript of Chemistry
Analytical chemistry is the science of obtaining, processing, and communicating information about composition and structure and matter. In other words, it is the art and science of what matter is and how much it exist.
Physical chemistry is the study of how matter behaves on a molecular and atomic level and how chemical reactions occur. Based on their analyses, physical chemists may develop new theories, such as how complex structures are formed. Physical chemists often work closely with materials scientists to research and develop potential uses for new materials.
All the chemicals in average waste are not the cause of the majority of environmental problems the world faces today, such as climate change and water pollution. Humans may be the main cause of that. Chemicals may help more than they hurt. Research in biological sciences and chemistry has revealed that industrial processes in chemistry and petrochemicals could play a role in developing solutions to environmental problems such as climate change, waste management, recycling, and energy efficiency – just to name a few.
The number of medical achievements that the science of chemistry has infulenced is enough to amaze anyone really. Without its help, the horrible disease that was small pox, wouldn't have been eradicated from existence. The genius, Bill Gates belives scientists can obliterate four different dieases at the least in the next fifteen years. For this reason, chemistry is arguably the most important science.
What is it?
The periodic table is a chart that arranges the chemical elements in a useful and logical manner. elements are listed in order of increasing atomic number, lined up so that elements which exhibit similar properties are arranged in the same row or column as each other. The Periodic Table is one of the most useful tools of chemistry and the other sciences.
The Five Main Fields of Chemistry
The Periodic Tables of Elements
Biochemistry is the study of the structure, composition, and chemical reactions of subtances in living systems. Biochemistry emerged as a separate discipline when scientists combined biology with organic, inorganic, and physical chemistry and began to study how living things obtain energy from food, the chemical basis of heredity, what fundamental changes occur in disease, and related issues. Biochemistry includes the sciences of molecular biology, immunochemistry, and neurochemistry, as well as bioinorganic, bioorganic, and biophysical chemistry
Organic chemistry is the study of
sturucture, properties, composition,
reactions and preperation of carbon-contaning compounds, which include not only hydrocarbons but also compounds with any number of other elements, including hydrogen (most compounds contain at least one carbon–hydrogen bond), nitrogen, oxygen, halogens, phosphorus, silicon, and sulfur.
Inorganic chemistry is concerned with the properties and behavior of inorganic compounds, which include metals, minerals, and organometallic compounds. While organic chemistry is defined as the study of carbon-containing compounds and inorganic chemistry is the study of the remaining subset of compounds other than organic compounds, there is overlap between the two fields (such as organometallic compounds, which usually contain a metal or metalloid bonded directly to carbon).
The Importance of Chemistry
What is Chemistry?
The dictionary definition of chemistry is; The branch of science that deals with the identification of the substances of which matter is composed; The investigation of their properties and the ways in which they interact, combine, and change; And the use of these processes to form new substances.

5 Interesting Facts
1. While Dmitri Mendeleev is cited as the
creator of the modern periodic table, his
table was just the first to recive scientific
credibility, it was not the first to table organized by periodic properties.
2. There are 90 elements on the periodic table that occur in nature. The rest are strictly manmade.
3. The main difference between the modern periodic table and Mendeleev's periodic table is that Mendeleev's table arranged the elements in order of increasing atomic weight while the modern table orders the elements by increasing atomic number.
4. There is room for exactly 118 elements. Elements aren't discovered or created in atomic number. Scientists are working on creating and verifiying element 120, which will change the appearence of the table.
5. Most of the elements on the periodic table are metals. The alkali metals, alkaline earths, basic metals, transition metals, lanthanides and actinides all are groups of metals.
