В некоторых школах химию начинают изучать в 7 class, in others only in the 8th grade. Chemistry is a heavy science, but it is notoriously interesting and important. People still do not know everything about this science. Every year, chemists discover something new on our planet.
Who is a chemist?
Consider the definition in more detail.A chemist is a scientist or specialist in the field of chemistry, who has received a special education. Such scientists study chemical elements, that is, matter and its properties. They use the accumulated knowledge to study and discover new substances.
The most important discoveries in the field of chemistry
In chemistry there are hundreds of important discoveries,for example, the detection of such a chemical element as oxygen, the study of the chemical structure, the detection of electrons, the radioactivity of certain chemical elements, the creation of a periodic table of elements, and many others. All these discoveries are handled by a chemist who first studies them and then, on the basis of his knowledge, tries to draw the necessary conclusions and discover something of his own.
Russian chemists
Russian chemists do not lag behind others. Every year the sphere of chemistry and biology chooses more and more students and students.
Russia is famous for scientists, for example, such asMikhail Vasilyevich Lomonosov, who studied molecular-kinetic theory, Dmitri Ivanovich Mendeleev, who created an indispensable periodic table of all chemical elements and wrote the first organic textbook in Russia, Vladimir Vasil'evich Markovnikov (studied oil and many other substances).
Пожалуй, самый известный русский химик – это Dmitri Ivanovich Mendeleyev, which students are told about in the very first lessons of chemistry. This scientist-chemist created a table of periodic elements, due to which it is much easier and more accessible to study chemistry. In addition, he wrote several hundred works, conducted thousands of experiments and studies. His work students are studying at universities. For many years Dmitry Ivanovich worked at the university, where he lectured to ordinary students. Today all his works are a real storehouse of knowledge for beginning chemists.
Chemistry is a very difficult subject, but necessaryin real life. Chemistry studies everything that is around us, which allows us to live on this Earth. Thanks to this science, we learned much more about our planet. A real chemist must love this science, constantly learn something new.
