ATPT - The Atom and the Periodic Table (Lesson)
The Atom and Periodic Table
Introduction
By now, you know that all substances are made from atoms. There are just over one hundred different types of atoms, called elements. Elements can join together in millions of different combinations to make all the substances in the universe. The Periodic Table organizes these elements according to chemical and physical properties. It may look like any other chart to you now, but by the end of this module you will be an expert at locating the different properties of elements on the Periodic Table.
Atomic Number and Average Atomic Mass
The atom and the periodic table are the focus of this segment of Chemistry Matters, produced by Georgia Public Broadcasting. The students explore periodic trends as well as atomic number and average atomic mass. While you watch, feel free to pause the video to take notes in the note taking guide document below. The key to the questions within the document is also included below.

Identify the Missing Subatomic Particles Practice
Use the periodic table below to identify the missing subatomic particles in the Subatomic Particles Chart. (Hint: Isotopes may have different masses than the periodic table lists. The periodic table lists average atomic mass, not mass number.) Check your answers by clicking on the covered numbers.
