Dmitri Mendeleevpresented his periodic table of the elements based on increasing atomic weight on March 6, 1869, in a presentation to the Russian Chemical Society. While Mendeleev's table was the first to gain some acceptance in the scientific community, it was not thefirst tableof its kind. ...

In 1869, Russian chemist Dmitry Mendeleyev published the first periodic table of elements, writing the chemical properties and masses of each element on cards. He arranged the cards according to increasing atomic mass and found that elements of similar properties appeared at regular intervals. But...

From the first periodic tables in the 19th century on, individual researchers have used different colour regimes. While standardization may play an obvious role in chemistry and its diagrams, all the more impressive is the anarchistic use of colour in the respective diagrams up to today. This ...
gallium做关键词定位至倒数第三句，但这句话只是说命名为GA，没说支持什么，往下看说GA的发现支持了元素周期律，而问题刚好是问GA的发现支持了什么，所以答案是C，元素周期表的组成规律，也就是元素周期律。
What elements on the periodic table are nonmetals? What elements on the periodic table are gases? What element family does bohrium belong to on the periodic table? What are the first 20 elements and their atomic numbers? What is the heaviest element on the periodic table?
Finally, in 1869, the German Lothar Meyer and the Russian chemist Dmitry Ivanovich Mendeleev almost simultaneously developed the first periodic table, arranging the elements by mass. However, Mendeleev plotted a few elements out of strict mass sequence in order to make a better match to the ...
Dmitri Mendeleev is known as the father of the periodic table of elements, and rightly so. He ordered the elements correctly based on their properties, which helped predict the discovery of new elements. But he wasn’t the first to come up with the idea of periodicity of elements, or the...
