How many of the five chemists who have influenced human progress do you know? In the history of chemical development, countless chemical ancestors have dedicated themselves to the development of chemistry, among which many outstanding chemists have emerged, here, we have taken stock of five chemists who have influenced human progress, see if you know?
Lavoisier: The father of modern chemistry
Lavoisier (26 August 1743 – 8 May 1794) was a French chemist and biologist. He advocated and improved quantitative analysis methods and used them to verify the law of conservation of mass; created the oxidation theory to explain experimental phenomena such as combustion, and pointed out that animal respiration is essentially slow oxidation. These epoch-making contributions made him the greatest chemist in history.
Avogadro: The proposer of the molecular hypothesis
Avogadro (9 August 1776 – 9 July 1856) was an Italian chemist and physicist. In 1811, he proposed Avogadro's law, created the concept of the molecule, and elaborated on the difference between the molecule and the atom. This is a useful complement and important development to atomism. But it was not until 1860 that the idea of molecular theory was accepted by the scientific community. In honor of this great scientist, the number of particles contained in 1mol of matter was named the Avogadro constant.
PAULING: Twice-awarded the Nobel Prize
Pauling (February 28, 1901 – August 19, 1994) was an American chemist. He introduced quantum mechanical methods into the field of chemistry and fundamentally changed the face of the discipline. Pioneering research on chemical bonds that makes chemistry more precise and rigorous. In 1939, the book The Nature of Chemical Bonds was published, establishing his position as a generation of grandmasters. He was awarded the Nobel Prize in Chemistry in 1954 for his work on chemical bonds, and in 1962 he was awarded the Nobel Peace Prize for his actions against the ground testing of nuclear bombs.
Mendeleev: Release of the first periodic table of elements
Mendeleev (February 7, 1834 – February 2, 1907) was a Russian chemist. He proposed the periodicity of elements in a paper entitled "The Relationship between Elemental Properties and Atomic Weight" and published the first periodic table of elements. The chemical elements were finally arranged in a rational order, and some elements that had not yet been discovered were foreseen. Today, chemistry textbooks are accompanied by a periodic table, which in itself is an incomparable tribute to a scientist.
Nobel: The most widely known chemist
Nobel (21 October 1833 – 10 December 1896) was a Swedish chemist, engineer, inventor and inventor of explosives. An outstanding chemical engineer, a successful businessman. He was probably the most famous in the field of chemistry and established the Nobel Prize. He risked his life to invent safety explosives, which greatly promoted the development of the world. At the same time, this great invention was also widely used in warfare. Nobel, a legend, gained a great deal of wealth for scientific achievements, immortalized for the great way in which wealth was handled.
Chemistry is beautiful, chemistry is the key to human progress, in time, I believe that our country can continue to appear in the annals of human chemistry history of great chemists!
