i know a song about it it is "do u know the first ten elements of the Periodic Table there's hydrogen, helium, lithium, borileam, boron, carbon, nitrogen, oxygen, florine, and neon"
Mendeleev arranged the elements in a table in the increasing order of atomic masses and repeating periodic properties. In the modern long-form of periodic table, the elements are arranged in the increasing order of atomic number and repeating periodic properties.
chemistry
The Periodic table is organized in several ways: 1) They are organized according to increasing atomic number, which usually does coincide with increasing atomic mass. So, if you look at the periodic table from left to right, or top to bottom, you will notice that the atomic numbers become larger. 2) The periodic table is organized horizontally into rows which are called "periods." Each element from left to right in a period gains a proton. So, in the first period, H has one proton, and He has two protons. 3) Now, the periodic table is also arranged into a system vertically as well. These vertical rows are called "groups," and are arranged according to their chemical characteristics and properties. These groups are denoted by A or B, group A being representative elements, and group B being transition metals. Those are three ways that the periodic table is organized. Furthermore, the periodic table also categorizes the elements into 3 groups: metals, metalloids and non-metals.
Many more elements are known today then when Mendeleev laid out his table. In addition, he arranged his table by atomic mass and there are places in the periodic table where mass does not always increase. An example is between tellurium and iodine.
Arsenic did not create the first periodic table. The first periodic table was created by Dmitri Mendeleev, a Russian chemist, in the 1860s. Other scientists had organized elements in other ways prior to the invention of Mendeleev's periodic table, but the other methods were criticized and did not catch on.
The periodic table is just a way of grouping elements according to their atomic numbers. It helps scientists to understand why different elements react in different ways.

Sounds like the Periodic Table of the elements.
because the elements can combine in many different ways and thus there are nearly unlimited possible compounds.

He formulated the Periodic Law and revised and predicted the Periodic Table of Elements in some important ways.

Yes, we will forever be adding new elements to the periodic table as we figure out new ways to make them; however, most of what you see now will stay the same.

The periodic table comprises of 118 different fundamental elements which combine in many different ways to form all substances known to man.
