In this lesson, you will learn more about the atom's basic structure and the positive and negative charges of its subparticles. This lesson lays the groundwork for further study of static and current electricity by focusing on the idea of positive and negative charges at the atomic level.
Explore the following Web pages to understand more about the structure and characteristics of atoms.
- Structure of Matter: Read Intro and Atoms.
- All About Atoms: This resource has only a couple of pages to it. You can click on a particle to learn more about it.
As you explore the Web pages, answer these questions on your Introducing Atoms student sheet. Be prepared to discuss your answers with the class.
- What makes the elements in the Periodic Table different?
- What is the name for the center of the atom containing the protons and neutrons?
- What kinds of electrical charges do protons, electrons, and neutrons have?
- What does it mean if an entire atom has a neutral charge?Describe the movement of the electrons.
- What can happen to the atomic particles when you rub two objects together?
- What happens to an object that loses electrons?
- What happens to an object that gains electrons?
- What happens to an object with a positive charge and an object with a negative charge?
- What causes the particles of the atom to stay together?
