The periodic table is not set in stone. There are blank spaces the signify elements that haven't been discovered yet. A way to find new elements is by putting existing elements together, and hope a new element is created from them.
Elements are the building block of our universe, and the periodic table orders them in a very clever way. Dmitri Mendeleev invented the periodic table, and organized them according to their atomic masses. Later Henry Moseley found that the number of protons in the nucleus corresponded exactly with an element's spot on the periodic table. He arranged his periodic table according to the atomic number. Dmitri Mendeleev however, made his discovery before protons were even discovered. Other than periods and groups, the periodic table organizes the periodic table in to blocks: the s block, d block, p block, and the f block. These block reveal more about how the electrons are arranged, where they are likely to be, and which electrons are the valence electrons. These all apply, except for the f-block, where periodicity is no longer recognized. In 1945, Glen Seaborg came up with the Actinide series that went along with the Actinide series, but he also placed another row he imagined that begins with the atomic number 122-? These elements still remain to be found in nature, or synthesized in a laboratory. To synthesize these elements, they purify their target material, apply the material to their target, collide second material with target, and then separate the new heavy element. They also use homologues, which are elements that are either in the same group, or are believed to have similar chemical properties to the heavy elements they wish to study. We are still not sure whether or not the periodic table is completely reliable, so chemists are discovering new elements, and seeing whether or not they correspond to the periodic table.
Chemists in the19th century were not aware of electrons or protons. Most of their information came from measurement of atomic masses and other observed physical and chemical properties. Dmitri Mendeleev is often considered the father of the periodic table. The arrangement he eventually came up with was so successful that it has endured through the discovery of dozens more elements, as well as new ways of understanding atoms that Mendeleev and his contemporaries could never have imagined. ~Mabel~
How an element reacts with water is directly related to how its electrons are arranged.

The periodic table is a great way to organize the elements and to explain the relationships between them.
