Brief Discussion of Periodic Table Elements 1. Introduction We know that 118 elements have been discovered so for. A table in which similar elements are placed in the same group is called a periodic table. A periodic table is the most significant achievement in the field of chemistry. It serves the students to know the properties of elements in a systematic way. It is the basic framework to study the periodic variations in the physical and chemical behavior of elements or their compounds. The modern periodic table is used to organize all the known elements. Elements are arranged in the table by increasing the atomic number. In the modern periodic table, each element is represented by its chemical symbol (Levi and Rosenthal, 1984; Kitaev, 2009). Columns of the periodic table are called groups. Elements in the same group have similar properties. For chemistry students and teachers: The tabular chart on the right is arranged by an Atomic number. The first chemical element is Hydrogen...
