The information about Marie Curie and radium is urgent, thank you first

When Marie Curie decided to write about Dr.**, Henri Berclerc was working on experiments with uranium salts, a rare metal. Berclery V discovered that uranium salts emit a ray similar to sunlight that penetrates opaque black paper. This caught Marie Curie's attention.

Both Pierre and I were very interested in this newly discovered ray and were determined to study its properties. If you want to study this new ray, you first have to measure it precisely and quantitatively. So I took advantage of the characteristics of the electroscope discharge, but instead of using a normal electroscope like Berkeler, I used a device that could make quantitative measurements.

It didn't take long for us to get interesting results. ......The emission of such rays is actually one of the atomic properties of the uranium element and has nothing to do with the physical and chemical properties of the uranium salt. Any uranium salt, as long as it contains more uranium, the stronger the radiation it emits. ”

I then wanted to find out if there were other elements that could emit the same rays as uranium salts. Soon I was in the mood for thorium, which had the same properties. Just as I was preparing to do further research on the radioactivity of uranium and thorium, I discovered a new and interesting fact.

This is different from the text, where Marie Curie studied the radioactivity of other elements.

She examines the ore by radioactive methods. And it was thought that "if these ores can produce the same rays, then it can be determined that they contain uranium or thorium." If the radioactive intensity of these ores is proportional to the composition of uranium or thorium contained in the ores, then there is nothing surprising, but in fact it is quite different, and some ores are three or four times more radioactive than uranium.

I carefully analyzed this phenomenon and came up with only one explanation: in this ore there is an unknown element that is much more radioactive than uranium and thorium. Pierre agreed with my analysis, and I wanted to discover the unknown element as soon as possible.

It was clear from here that they were about to discover the unknown.

At first, I didn't expect this ore to contain a large number of new elements, because it had been studied and analyzed over and over again. My initial estimate was that the ore was not more than 1 part per million in the amount of new elements that were scavenged. As we continued to dig deeper, we found that my estimate was still too high, and the true content was much less than one part per million.

This is all the more indicative of the extremely radioactive nature of this new element.

If we had known from the beginning that it was very small, I don't know if I would have had the determination and courage to persevere, because we were poorly equipped and underfunded. Looking back now, I was thankful that I didn't know it would be so difficult, so I was very determined.

After I actually started to do it, although I found that there were many difficulties, the results of my research continued to appear, so I was much more motivated and didn't think about those difficulties anymore. After several years of diligent work, we were able to isolate this new element, which is what we know today as radium. ”

In 1898, a new radioactive substance was recognized. Radium. The scientist who discovered radium was Marie Curie, who was also known as the "mother of radium" because of this discovery.

Marie Curie was born in Poland in 1867, the son of a professor of physics at a higher school. From an early age, Marie Curie was interested in various scientific phenomena.

In 1891, Marie Curie went to the University of Paris to continue her studies, during which time she met with the French professor of physics, Pierre Fried. Curie met and became husband and wife.

At the time, Marie Curie was interested in uranium rays and conducted in-depth research with her husband. After extensive experimentation, she discovered a substance that emits radiation like uranium, and called these hail-emitting substances "radioactive elements".

In the process of collecting minerals, Marie Curie discovered an unknown substance that is more radioactive than uranium. In the scientific community, if you want to announce that you have discovered a new element, you must come up with evidence. So, Marie Curie was determined to find the evidence.

Eventually, they bought cheap bituminous uranium ore slag and experimented with it. The rudimentary experimental equipment and difficult environment did not shake their determination to find new elements.

Ignoring the damage caused by radioactive substances to the body, the couple finally extracted a new element from dozens of tons of waste residue and named it "radium".

Marie Curie discovered radium with amazing perseverance, and if we encounter difficulties in the process of learning, we must also learn from her spirit of overcoming difficulties.
