![]() So, don’t delay and download the PDF from the link given below. It is a synthetic element that was first synthesized in 2002. The heaviest element on the periodic table is oganesson (Og), which has an atomic number of 118.The periodic table contains both naturally occurring elements and synthetic elements that have been created in a laboratory.The elements in a period have the same number of electron shells. The horizontal rows of the periodic table are called periods, and there are seven periods in total.Group 1, also known as the alkali metals, is located on the far left of the table, while Group 18, also known as the noble gases, is located on the far right. ![]() The elements in the periodic table are organized into 18 groups, numbered 1 to 18. A necessary prerequisite to the construction of the periodic table was the discovery of the individual elements.Elements in the same group or column of the periodic table have similar chemical properties due to their similar electron configurations.The modern periodic table is arranged in order of increasing atomic number, which reflects the number of protons in the nucleus of an atom.He arranged the elements in order of increasing atomic mass and noticed that the properties of the elements repeated in a periodic manner. The periodic table was first proposed by Russian chemist Dmitri Mendeleev in 1869.The periodic table is an essential tool for understanding the properties and behavior of the elements, as well as for predicting their chemical reactions and interactions. Noble gases: located in the far right column of the periodic table, they are generally inert and unreactive due to their stable electron configurations.Metalloids: located along the zigzag line on the periodic table, they have properties of both metals and non-metals.Non-metals: located on the right side of the periodic table, they are typically dull, brittle, and poor conductors of heat and electricity.Metals: located on the left side of the periodic table, they are typically shiny, malleable, ductile, and good conductors of heat and electricity.The periodic table is divided into four main categories of elements: The elements in a group share similar properties, and the elements in a period have the same number of electron shells. The rows of the periodic table are called periods, and the columns are called groups or families. Each element is represented by a unique symbol, typically consisting of one or two letters.
