What contributions did Marie Curie make, and Marie Curie s main contributions

Research Interests: 1. The radioactive elements polonium (PO) and radium (Ra) were discovered.

2. The idea was put forward that - rays (which are now known to be made up of electrons) are negatively charged particles.

Scientific achievements. Marie Curie was the founder of modern radioactivity theory and had a profound influence on modern science. She pioneered the theory of radioactivity and discovered two radioactive elements, polonium (Po) and radium (Ra), and won two Nobel Prizes (Nobel Prize in Physics and Nobel Prize in Chemistry, respectively), and is the only person to win two Nobel Prizes in science.

Major contributions: the discovery of two new elements, polonium and radium.

On December 26, 1898, in her report to the French Academy of Sciences, Marie announced that they had discovered a new element, radium, which was a million times more radioactive than uranium. It is the culmination of the great love of Pierre Curie and his wife Marie Sklodowska after 3 years of marriage.

Radium is a highly radioactive element that is in the periodic table of chemical elements in period 7, group IIA, atomic number 88, element symbol RA. Pure radium metal is virtually colorless, but when exposed to air, it reacts with nitrogen to produce the black radium nitride (Ra3N2).

Marie Curie was born on November 7, 1867, in Warsaw, Kingdom of Poland, to a family of secondary school teachers. In September 1891, he went to Paris to study, and in November he entered the Department of Physics of the Faculty of Science of the University of Solburne (i.e., the University of Paris).

In April 1894, he was introduced by Joseph Kowalski, a Polish scholar and professor of physics at the University of Forborg in Switzerland, to get acquainted with Pierre Curie in order to make use of the better-equipped laboratory led by Curie.

In April 1895, Marie Skrodovska's "Radioactivity of Compounds of Uranium and Thorium" was read by Lippmann at the Academy of Sciences. On July 26, 1895, Marie married Pierre Curie in the Paris suburb of So. Marie Curie is a teacher at the girls' secondary school.

In June 1934, Marie Curie was admitted to the Sancerromo sanatorium in Haute-Savoie. On July 4, he died of pernicious anemia (caused by radium) in a nursing home.

Marie Curie was the first person in history to win two Nobel Prizes, and that was in two different fields.

She was Marie Curie of China, who gave up her life in the United States to teach at Tsinghua University, but was imprisoned at the age of 62.

Marie Curie's main contribution was the practicality and experience of "radium".

At that time, the scientific community had various characteristics of the research on "radium". But it's still relatively shrunken in use.

Marie Curie's team has implemented large-scale medical applications in the application of radium. The medical effect is obvious. The experience accumulated during the application process has provided a large amount of initial experience and records for the later medical use of radioactive elements.

Curie and his husband discovered many radioactive elements, such as radium.
