Overview

The goal of this lesson is mainly to get students re-familiarized with basic electrostatics. They will watch a short video to help them recall the parts of an atom and basic subatomic particle behavior. They need to come away with the understanding that electrons are very small (relative to protons and neutrons), negatively charged, and on the "outside" of an atom.

Student Directions and Resources


The goal of this lesson is to remind you of the parts of the atom, and some basic properties of each. At the end of this lesson you will answer some questions to test your understanding.

1. How Do Electrons Behave?


Watch the video below and answer the questions that follow.


Question 1.1

What charge does an electron have?

  positive
  negative
  neutral


Question 1.2

Where do electrons "live"?

  in the nucleus
  outside the nucleus
  inside the neutrons
  next to the protons


Question 1.3

When a neutral atom gains or loses electrons, that atom is considered charged. Why do atoms gain and lose electrons, while protons and neutrons generally aren't exchanged between atoms?

  Electrons are negatively charged.
  Electrons are very small (relative to protons and neutrons).
  Electrons are on the outside.
  Electrons are constantly moving.
