<p>Earlier in this tutorial, we talked about different “models” of the atom. In science, one of the uses of models is that they can help us to understand the structure of something that we can't see. In the case of the atom, models help us to build a picture in our heads of what the atom looks like.</p>

<h2>Discussion: Building a Model of an Atom</h2>
<div class="ns-school-defn">
<p>If you are interested, try to build a model of an atom. You can represent any <a data-lesson="elements" data-subject="chemistry" data-tutorial="classification-of-matter" href="https://app.ulearngo.com/chemistry/classification-of-matter/elements">element</a> you wish. Before you start, think about these questions:</p>
<ul>
<li>
<p>What information do I have about the structure of the atom? (e.g. what parts make it up? how big is it?)</p>
</li>
<li>
<p>What <a data-lesson="materials" data-subject="chemistry" data-tutorial="classification-of-matter" href="https://app.ulearngo.com/chemistry/classification-of-matter/materials">materials</a> can I use to represent these parts of the atom as accurately as I can?</p>
</li>
<li>
<p>How will I put all these different parts together in my model?</p>
</li>
</ul>
<p>Share your ideas in the discussion (comments) section below and then plan how you will build your model. Once you have built your model, discuss the following questions:</p>
<ul>
<li>
<p>Does your model give a good idea of what the atom actually looks like?</p>
</li>
<li>
<p>In what ways is your model <em>inaccurate</em>? For example, we know that <a data-lesson="orbital-shapes-and-valence-electrons" data-subject="chemistry" data-tutorial="chemistry-essential-ideas" href="https://app.ulearngo.com/chemistry/chemistry-essential-ideas/orbital-shapes-and-valence-electrons">electrons</a> <em>move</em> around the atom's nucleus, but in your model, it might not have been possible for you to show this.</p>
</li>
<li>
<p>Are there any ways in which your model could be improved?</p>
</li>
</ul>

Discussion on Atomic Models

Chemistry generally explores the substances of which matter is composed, the investigation of their properties and reactions, and the use of such reactions to form new substances. 

Chemistry

Explore the essential ideas in chemistry, including the scientific method, laboratory skills and safety, states of matter, measurement uncertainty, models of the atom, electronic configurations, and more.
