Answer :
- The periodic table is a tabular arrangement of chemical elements based on their atomic numbers, electron configurations, and recurring chemical properties.
- It features an 18 by 7 grid and includes specific groups and periods that highlight similar and progressive element attributes. This layout aids in understanding and predicting chemical behavior.
- The table can also be deconstructed into four rectangular blocks: the s-block to the left, the p-block to the right, the d-block in the center, and the f-block at the bottom.
- This organization helps in understanding the trends in various chemical properties, such as electronegativity, ionization energy, and atomic radius.
- Columns, known as groups, contain elements with similar properties, and rows, known as periods, showcase a progression of these properties.
