118 Elements And Their Symbols And Atomic Numbers: A Periodic Table of Elements is an essential tool in chemistry, designed to help users quickly reference chemical elements, which are arranged to highlight periodic trends in their properties. Typically, the table displays only the element's symbol rather than its full name. It is widely utilised by scientists, professionals, teachers, and students of chemistry for the identification and study of chemical elements. According to the periodic law, the properties of elements are periodic functions of their atomic numbers. The periodic table comprises 118 elements.

The symbol is a one or two-letter abbreviation used to represent an element, while the atomic number refers to the number of protons in the nucleus of an atom of that element. These conventions ensure consistency in identifying and writing chemical symbols across all elements. The symbol acts as a shorthand notation for each element's name in formulas and equations, facilitating more efficient and precise communication within the field of chemistry.
