Are you interested in the history of chemical development? Tell me your most impressive story about the history of chemistry?

Interested. When Madame Curie inspected pitchblende and copper mine, she found that these two minerals contained a substance more radioactive than uranium or thorium. She realized that this is a new element that has not yet been recognized. She said to her husband, "If this new element can be proved in the future, I want to call it polonium to commemorate my motherland-Poland."

Although Marie Curie lived abroad and married a French scientist, pierre curie, she loved her motherland since she was a child and never forgot her motherland occupied by the Russian Empire. She wants to win pride and glory for her motherland by naming new elements! Entrust her with patriotic passion like fire. "ok!" Pierre curie said: "Poland is your motherland, and it can also be said that it is my motherland!" The intense work began, and it was eliminated day and night, and the scope of research became smaller and smaller. 1in July, 897, they separated out a new radioactive element from some minerals containing bismuth, which is similar in chemical properties to bismuth and 400 times more radioactive than pure uranium. "Ah, new elements, polonium, polonium." Madame Curie threw herself into her husband's arms and shouted excitedly, "polonium!" " Two lines of tears spilled on her husband's chest.

"Polonium, Poland! Poland, hey! " Pierre also cheered from the bottom of his heart.
