How did he arrange his periodic table
WebMendeleev arranged the elements in his periodic table ordered by atomic weight or mass. He arranged the elements in periods and groups in order of their increasing atomic weight. He placed the elements with similar properties in the same group. However, he did not stick to this arrangement for long. Web12 de abr. de 2007 · This year marks the 100th anniversary of the death of one of the most famous scientists of all time, the Russian chemist Dmitri Ivanovich Mendeleev (1834–1907).

WebThis was mainly because the idea on atoms being produced up of smaller sub-atomic particles (protons, neutrons and electrons) had did been developed. Nevertheless, the basis of the modern periodic table was well established press even used at predict the properties of undiscovered books long before the concept of the atomic number is developed. WebJohn Dalton did not arrange the periodic table. However, he brought in his atomic theory which had five postulates that are still valid. With this development, it became clear that Mendeleev has arranged the periodic table in order of increasing atomic number. This helped the chemists in discovery of new elements. Thank Writer Blurt
