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”.
