Understanding the Structure of the Periodic Table
The periodic table is organized into rows (periods) and columns (groups or families). The arrangement allows for the categorization of elements that exhibit similar properties.
Key Features of the Periodic Table
1. Atomic Number: This is the number of protons in the nucleus of an atom and determines the element's identity.
2. Element Symbol: A one- or two-letter abbreviation for the element's name (e.g., H for hydrogen, O for oxygen).
3. Atomic Mass: The average mass of an element's atoms, accounting for the isotopes present.
4. Groups/Families: Vertical columns that group elements with similar properties (e.g., alkali metals, alkaline earth metals, halogens).
5. Periods: Horizontal rows that represent elements with increasing atomic numbers.
