The discovery of a variety of elements with predicted properties explains the effectiveness of the periodic table.
Dmitri Ivanovich Mendeleev is a scientist from Russia; he mainly contributes to explaining the periodic table or help in developing the periodic table. The periodic table is also referred to as Mendeleev periodic table. In his table, all the elements which have been identified are organized based on mass, chemical properties, and fundamental properties of an element.
Also, from the periodic table, he determined that all the properties of the element are relatable to the atomic mass of an element. He also arranges all the elements in such a manner that elements that have similar properties are grouped in the same column. In the table, the molecule of hydrogen is not very well explained with its properties.
Newly discovered elements can easily be added to the table because some columns yet to be vacant for new elements. The effectiveness of the periodic table is explained by new research on a variety of elements.
