The periodic table of elements is a tabular display of the chemical elements, which are arranged by atomic number, electron configuration, and recurring chemical properties. The standard form of the table was devised by Dmitri Mendeleev in 1869, who used it to predict the properties of unidentified elements yet to be discovered or synthesized.
The periodic table of elements is a chart that shows how chemical elements are related to one another. The table is organized so that elements with similar properties are grouped together. This makes it easy to find information about any given element.
The periodic table has been around for centuries, and it has helped chemists understand the world around them. It is an essential tool for anyone who studies chemistry, and it can be used to predict the behavior of new elements that have not yet been discovered. The periodic table is constantly evolving as new elements are discovered and new information about existing elements is uncovered.
It is a living document that reflects our current understanding of the chemical universe.

Periodic Table of Elements With Names
The periodic table of elements is a tabular arrangement of the chemical elements, ordered by their atomic number, electron configurations, and recurring chemical properties. The structure of the table shows periodic trends. The seven rows of the table, called periods, generally have metals on the left and nonmetals on the right.
The columns, called groups, contain elements with similar chemical behaviors. Underneath each element’s name is its atomic number—the number of protons in its nucleus—and its symbol. Elements are presented in order of increasing atomic number.
As you move from left to right across a period, or down a group, the elements generally become larger and their electrons more diffuse. This trend reflects increases in both nuclear charge (number of protons) and effective nuclear charge (nuclear charge minus shielding effects). In general, moving left to right within a period or upward within a group increases reactivity because it becomes increasingly easier to lose an outermost electron.
What are the 118 Elements in the Periodic Table?
The periodic table is a tabular arrangement of the chemical elements, organized on the basis of their atomic numbers, electron configurations, and recurring chemical properties. Elements are presented in order of increasing atomic number.
The first 94 elements occur naturally; the last 24 are man-made.
The first 82 elements have at least one stable isotope; this number drops to 56 for element 107 (bohrium), which has no stable nuclei. All 118 elements have been observed in the laboratory, but only 94 have been found in nature (as of 2020). The ordering of the elements within each period (row) and group (column) is largely explained by the periodic law.
Elements with similar electronic configurations tend to fall into the same vertical column on the periodic table. The columns on the left side of the table are called “groups”. There are 18 groups altogether; Groups 1–2 and 13–18 are numbered from 1 to 18 while groups 3–12 are lettered from A to L (skipping I).
The columns containing transition metals may be referred to as “B groups”, while those containing rare earth metals may be called “f block” or “inner transition series”.
What is the Name of 119 Elements?
The name of the 119th element is Ununennium.

What is the Newest Element on the Periodic Table 2022?
The newest element on the periodic table as of 2021 is nihonium, element 113. It was discovered in 2003 by a team of Japanese scientists and officially recognized by the International Union of Pure and Applied Chemistry in 2016. Nihonium is extremely unstable, with its most stable isotope (287Nh) only lasting for 20 milliseconds before decaying into other elements.
The periodic table of elements is a chart that shows how the chemical elements are related to each other. The elements are arranged in order of increasing atomic number, which is the number of protons in an atom. The periodic table can be used to predict the properties of new elements, and to understand the relationships between the elements.
