PERIODIC TABLE
The periodic table organizes chemical elements based on their atomic number, electron configuration, and recurring chemical properties. The elements are arranged in rows (periods) and columns (groups) with:
- Periods: Horizontal rows, each representing the filling of a new electron shell.
- Groups: Vertical columns, each containing elements with similar chemical properties and the same number of valence electrons.
The table includes metals, non-metals, and metalloids. Key categories include:
- Alkali Metals: Group 1, highly reactive metals.
- Noble Gases: Group 18, inert gases with full outer electron shells.
- Transition Metals: Located in the center, known for their ability to form various compounds.
The periodic table is a vital tool for understanding element properties and their relationships.Periodic Table
