The Periodic Table
Overview
Over a hundred elements have been discovered, and the Periodic Table organises every one of them in a pattern that reveals their properties at a glance. Knowing where an element sits in the table tells you whether it is a metal or a non-metal, how many outer-shell electrons it has, and how it is likely to react.
In this lesson you will learn how elements are arranged by atomic number into groups and periods, how to use the table to distinguish metals from non-metals, and why elements in the same group share similar chemical properties.
Objectives
- Understand how elements are arranged in the Periodic Table in order of atomic number, in groups and periods
- Identify an element as a metal or a non-metal according to its position in the Periodic Table
