Lesson 3
Theory Fundamentals:
Atoms, Elements and Compounds
In this lesson we will focus on elements and compounds.
In doing so we will present a rudimentary theory on the nature of elements and
compounds. That theory is Dalton's Atomic Theory. In later
lessons we will embellish his theory with additional details.
We will use the atoms of Dalton's theory (and modifications of it) to explain and add
to what you already know about elements and compounds, particularly the composition of
compounds.
As usual, you should begin this lesson by looking at the objectives for the lesson.
They tell you what you are expected to know and be able to do when you have completed this
lesson.
The Introduction includes descriptions and definitions of
"facts", "theories" and other aspects of scientific knowledge. After
looking at Dalton's Atomic Theory, we will consider the names and
symbols used to represent those atoms and look at how they combine
with one another to make compounds. As a part of measuring quantities of elements and
compounds you will learn about atomic weights and moles,
and, of course, the calculations associated with those quantities.
When you have completed the lesson be sure to wrap-up by taking the
self quiz and doing the problem set.
