Periodic table is a chart that lays out every single chemical element known to man, and all of their properties. In its current form it was first published in February 1869 by Dmitri Mendeleev (1834-1907), a Russian scientist who lived during the height of Russia's industrial and scientific growth, which increased also because of how the government implemented new educational policies and institutions.
The periodic table was first created by Dmitri Mendeleev in October 1869. It has, however, been revised numerous times since then due to advancements in scientific research. Not only did it help classify the elements into their respective periods, but also allowed scientists and researchers to come up with theories and procedures that would better describe the periodic trends, which is why it continues to increase in complexity.
Mendeleev's periodic table uses certain categories of elements in order to determine where they belong (periods) on the periodic table and how they react with each other. One of these categories is valence. Valence indicates the periodic trend that comes from each element's ability to gain, lose, or share electrons in order to achieve a closed shell. Mendeleev organized the elements according to these periodic trends in his periodic table, and it was this organization of periodic trends that brought him such success.
Periodic tables are a great tool for chemists of all ages and allows them to easily view all of the periodic trends associated with each element. This periodic trend is based on how they interact with other elements on their row, column, or diagonal in the periodic table. The periodic table also shows information such as melting point/boiling point, date of discovery, and the symbol. The periodic table is simple but organized which allows for easy reading that can be done quickly.
There are many periodic tables with different arrangements of elements in order to convey certain periodic trends. For example, one periodic table shows the periodic trends based on increasing atomic mass while another puts them together based on their periodic trends. While others are organized from periodic trends based on their state: i) Metallic ii) Non-metallic iii) Semi-metals and iv) Lanthanides and Actinides.
In this periodic table, the periodic trends of elements were placed side by side in order to show the periodic trends between them. By organizing them like this, it allows periodic trends to be easier seen than they would've been in a periodic table. This periodic trend is based on how each known element reacts with other elements found next to it in the same row, column or diagonal.
Periodic tables are not only simple but also help students relate periodic trends with a real periodic table to better understand the periodic trends. This periodic trend shows the periodic table organized by atomic number and mass, which is a periodic trend that many students can relate to, such as the periodic law of octaves.
Periodic tables are a great tool for people of all ages who want to learn new periodic trends. They help in organizing periodic trends for easier reading and understanding of periodic trends. There are many periodic tables that better explain periodic trends by their state or atomic number and mass which users can choose such as the well known periodic table of Dmitri Mendeleev. 
Table 1- Periodic table based on atomic number & Mass.
Table 2 Periodic table organized for elements according to periodic trends. The periodic table shows many different periodic trends such as ionization energy, valence, atomic radius and many more periodic trends.
Two periodic tables are shown in the above image, a periodic table with fewer rows which is easier to read and a periodic table that is more complex but shows more periodic trends. The periodic table shows many different periodic trends such as ionization energy, valence, atomic radius and many more periodic trends.
