“People have been doing this for a long time, but in the end there was a little bit of a natural basis" Dr. Weatherers

His interpretation included a creative leap. Mendeleev put on his table the elements of similar characteristics under each other in groups. And he left gaps between them to include new items that are expected to be discovered later.

“People have been doing this for a long time, but in the end there was a little bit of a natural basis,” Dr. Weatherers says. Or to say a law that meant it had to be arranged in some way. ”

The 150 years that separate us from those days have witnessed many fundamental changes in our understanding of matter. "It seems clear that Mendeleev did not know about the subatomic structure at the time," says Weatherers. So he based his work on atomic weights only, which were not necessarily known at the time.

After discovering protons, scientists realized that the atomic number of an element (the number of protons in its nucleus) is more important for the arrangement of elements. So the elements in the modern periodic table are arranged according to their atomic number, and not according to their relative atomic masses. We now know how to do this, and that relates to quantum mechanics, the arrangement of electrons in atoms, and so on.

Now, the number of elements exceeds 100, arranged according to the increasing atomic number. There are repeated patterns of object properties, and it is precisely this that gives the periodic table its name. Where elements with similar properties are arranged to form columns (groups). Today's periodic table is aesthetic and practical in nature. You can realize some properties of the element by looking at its position in the periodic table only, or by looking at its arrangement, and this makes the table extremely important for chemists.
Symmetry fun

This year, which was called the year of the periodic table, may represent the climax of his youth, too. Currently, the seventh cycle of the periodic table is complete in addition to the last which consisted of four elements in December 2015. This addition made it complete and even beautiful.

So, today we are lucky that the periodic periodic table has completed, and perhaps this perfection is the most remarkable of what the periodic table will ever reach.

Many scientists today are working on installing heavier elements (which are not present in their natural form), and if this goes on the right track, the face of the periodic table will change again.

If we happen and we get only one new element, we will have to add an eighth grade, it is the eighth session! The periodic table will lose some of its beauty at that time, as the prevailing belief among scientists today is that it is impossible to complete the eighth session of the table to remain as a memorial to the limited scientific capabilities.
