A brief introduction to the Periodic Table
4 likes1,828 views
The document provides an introduction to the periodic table. It explains that the periodic table arranges elements in a table according to their atomic numbers, so that elements with similar properties are in the same column. This allows chemists to easily reference properties of groups of elements. Each element is given a unique symbol and atomic number. The first 20 elements, their symbols and atomic numbers are also listed.

- 2. What is the Periodic Table? A tabular arrangement of the elements according to their atomic numbers so that elements with similar properties are in the same column. This is an easy reference chart for chemists to use to interpret the properties of groups of elements, rather than try to memorize all the properties of Syllabuselement each objective met: Recognize that elements are arranged in a systematic way 2 Atoms and The Periodic Table Prepared by JGL 12/27/2011
