Whether you are studying for your GCSE exams or just curious about how the elements are organized, this guide will help you break it down step by step. How is the Periodic Table Organized? 1. Periods (Rows) and Groups (Columns) Periods (Horizontal Rows): The Periodic Table has 7 periods . Each period represents a new energy level of electrons in atoms. As you move from left to right across a period, the properties of elements gradually change. Groups (Vertical Columns): There are 18 groups . Elements in the same group have similar chemical properties because they have the same number of outer-shell electrons. Check GCSE Exam Dates 2025 Main Element Groups in the Periodic Table 1. Group 1 – Alkali Metals Includes Lithium (Li), Sodium (Na), Potassium (K), etc. Very reactive, especially with water. Soft metals with low melting points. 2....
