The Periodic Table of Elements organizes elements based on properties and displays symbols and atomic numbers.
The Periodic Table of Elements is a chart that organizes all known elements based on their properties. Each element is represented by a symbol, typically one or two letters, located at the center of the element's box. Additionally, the table includes the atomic number (number of protons) listed usually in the upper left.
By reading the periodic table, one can determine essential information about elements. For example, looking at the entry for Aluminum, symbol Al, one can see it has an atomic number of 13. Elements are arranged in periods and groups on the table based on their properties, allowing scientists to predict behaviors and characteristics.
Three elements like Hydrogen (H), Oxygen (O), and Sodium (Na) provide valuable insights by their position and properties on the periodic table. Hydrogen, a nonmetal, has an atomic number of 1, while Sodium, a metal, has an atomic number of 11. Oxygen is a reactive nonmetal with an atomic number of 8.
