This aptitude of an atom to attain or displace the negatively charged element (electron) to reach a steady configuration or static gas arrangement is referred to as the Valency of an element. In order to attain the steadiest arrangement i.e., of a noble gas, the atom of an object makes efforts to acquire or displace electrons.

The symbols are generally drawn by using either the first or first two letters from the English name of the elements. Some have three letters, which denote newly synthesized elements, while some are given that designation temporarily.
The remaining elements are arranged according to periodic characteristics and trends.įor instance, Soft metals are placed in group 1A due to their high reactivity with water.Ī symbol is a sign, code, or character that represents a chemical element. Those arranged vertically are called ‘Groups’, and the ones horizontally are called ‘Periods’. Elements are organized in horizontal and vertical formats. The entire name is not used to denote them because the name and nature of some elements can be long and complex. A particular symbol represents Elements of the Periodic Table. Elements are organized in increasing order, i.e., increasing atomic number. These help you test your own yourself and help you prepare for your exams in a better way.

It can be tough for a beginner in chemistry to learn the names of all the elements in the periodic table. Therefore, it is indicated with the symbol 'Fe'. Silver is indicated by 'Ag' it is because its Latin name is “Argentum”. However, some elements' symbols have Latin roots. Most symbols are alike to the name of the element. Scroll down to learn more about the Periodic Table, its features, Symbols, Derivations of Symbols, Valency of Elements, Atomic numbers, and other information. There are 118 Elements in the Period Table.Įach of them has a different property and atomic number. This periodic law articulates that the attributes of Elements are the periodic functions of their atomic numbers. It follows Henry Moseley’s modern periodic law. Henry Moseley, an English Physicist, discovered the latest Periodic Table. Later, a new Periodic table came into being. Moreover, the ones which were known were not adequate and authentic. When he discovered the first periodic table, it did not satisfy all the requirements of a knowledge seeker regarding chemical elements. It employs the notion of the atomic mass of the elements. He is called so because he was the first person to invent and discover the Periodic table.
