GENERAL CHEMISTRY I Unit 7: The Periodic Table

---

The periodic table is a tabular arrangement of all the known chemical elements, organized based on their atomic number, electron configurations, and chemical properties. The elements are arranged in rows and columns, with elements having similar chemical and physical properties placed in the same vertical column (group) and elements with similar electron configurations placed in the same horizontal row (period). The periodic table provides a useful framework for organizing information about the elements and their properties, and it has many important applications in fields such as chemistry, physics, and materials science. By analyzing the relationships between elements in the periodic table, scientists have been able to predict the properties of new elements, discover new materials with specific properties, and develop a deeper understanding of the underlying principles that govern the behavior of matter and energy in the universe.
