Uranium and thorium were the first elements found.Uranium was recognized and recognized in 1789 by German chemist Martin Heinrich Claprot in Peach Blend ores.He devised the name of the element in Cheonwangseong.It was discovered just eight years faster than other scientists.Claprot was soaked in nitrate and melted in sodium hydroxide and promoted (such as sodium icyuranium) to create a yellow compound.He reduced charcoal and yellow powder and extracted black substances.60 years later, French scientist Ferrigo found uranium oxide.He also heated the salted uranium and potassium to separate metal uranium.Uranium's atoms were calculated at 120, but in 1872, Dmitry Mendelev was found to be 240 through his periodic rate method.This mass was found in 1882 by K. Jimmerman.
