The Building Blocks of Matter

The Building Blocks of Matter

An exploration of the fundamental components that make up all matter in the universe.

The Periodic Table

• The Periodic Table is a tabular arrangement of chemical elements, organized based on their atomic number, electron configuration, and recurring chemical properties.
• It consists of 118 elements, each represented by a unique symbol and arranged in order of increasing atomic number.
• The table is divided into periods (rows) and groups (columns), which help classify elements based on their properties and characteristics.
• The periodic table is a powerful tool for scientists to predict the behavior and properties of elements, as well as discover new elements and understand their relationships.
