Module Introduction

Module 1—Chemical Foundations

Module Introduction

 

element: a pure substance that cannot be broken down into simpler chemical substances by any physical or chemical means; consists of only one kind of atom

 

ion: an entity with a net positive or net negative electrical charge due to the loss or gain of one or more electrons

 

ionic compound: a pure substance formed from the bond between a metal and a non-metal

 

molecular compound: a pure substance formed by covalently bonded non-metal atoms

 

kinetic molecular theory: the idea that the smallest entities of a substance—atoms, ions, or molecules—are in continuous motion, colliding with each other and objects in their path

Throughout Module 1 you will be examining fundamental science and chemistry concepts in the context of nuclear technology. You will examine

  • science and technology in society

  • elements and ions

  • ionic compounds

  • molecular compounds

  • chemical change and the kinetic molecular theory

In the context of nuclear technology, the question addressed in Module 1 is as follows:

 

What are the roles of modelling, evidence, and theory when explaining and understanding the structure, bonding, and properties of ionic and molecular compounds?

A photograph is shown of a Canadian postage stamp. The stamp contains diagrams of the outside of a nuclear power plant and of a high voltage transmission tower. In the upper- left corner of the stamp is a drawing of a white dove carrying an olive branch in its beak. The title above the dove states “Peaceful Uses”.
