The periodic table is a tabular arrangement of chemical elements, organized based on their atomic number, electron configuration, and recurring chemical properties. It provides a systematic way to classify and study the elements, showcasing their relationships and patterns. The periodic table is a fundamental tool in chemistry, serving as a reference for scientists, students, and researchers worldwide.

This periodic table consists of a table structure with rows and columns. Each element is represented by a cell within the table, containing information about the element’s symbol, atomic number, and atomic weight.
The table is divided into several blocks to highlight different groups of elements. The blocks are represented by different background colors:
- The “s-block” elements are highlighted in light orange.
- The “p-block” elements are highlighted in light blue .
- The “d-block” elements are highlighted in light gray.
- The “f-block” elements are highlighted in light pink.

The table follows the traditional format, with periods (rows) numbered from 1 to 7 and groups (columns) numbered from 1 to 18. The elements are placed in their respective positions based on their atomic number and electronic configuration.
The table also includes the element names and atomic weights below the element symbols. The atomic weights are given in atomic mass units (u) and represent the average mass of the isotopes of each element.
By using this periodic table, one can quickly locate an element and gather essential information about its atomic properties and characteristics. It serves as a valuable tool for studying and understanding the vast array of chemical elements that make up the building blocks of matter.
