Am really impressed with the tutorial 🥰🥰

I have been enjoying this method honestly... Read about 50% already 😌

<h2>Metals</h2>
Examples of metals include copper (\(\text{Cu}\)), zinc (\(\text{Zn}\)), gold (\(\text{Au}\)), silver (\(\text{Ag}\)), tin (\(\text{Sn}\)) and lead (\(\text{Pb}\)). The following are some of the properties of metals:

<ul>
<li>
Thermal conductors
Metals are good conductors of <a data-lesson="calorimetry" data-subject="chemistry" data-tutorial="thermochemistry" href="https://app.ulearngo.com/chemistry/thermochemistry/calorimetry">heat</a> and are therefore used in cooking utensils such as pots and pans.
</li>
<li>
Electrical conductors
Metals are good conductors of electricity, and are therefore used in electrical conducting wires.
</li>
<li>
Shiny metallic lustre
Metals have a characteristic shiny appearance and are often used to make jewellery.
</li>
<li>
Malleable and ductile
This means that they can be bent into <a data-lesson="molecular-shape" data-subject="chemistry" data-tutorial="bonding-atomic-combinations" href="https://app.ulearngo.com/chemistry/bonding-atomic-combinations/molecular-shape">shape</a> without breaking (malleable) and can be stretched into thin wires (ductile) such as copper.
</li>
<li>
Melting point
Metals usually have a high melting point and can therefore be used to make cooking pots and other equipment that needs to become very hot, without being damaged.
</li>
<li>
Density
Metals have a high density.
</li>
<li>
Magnetic properties
Only three main metals (iron, cobalt and nickel) are magnetic, the others are non-magnetic.
</li>
</ul>
You can see how the <a data-lesson="properties-of-metals" data-subject="chemistry" data-tutorial="bonding-atomic-combinations" href="https://app.ulearngo.com/chemistry/bonding-atomic-combinations/properties-of-metals">properties of metals</a> make them very useful in certain applications.

<h2>Discussion: Looking at metals</h2>
<div class="ns-school-defn">
<ol>
<li>
Collect a <a data-lesson="atomic-and-atomic-mass-number" data-subject="chemistry" data-tutorial="chemistry-essential-ideas" href="https://app.ulearngo.com/chemistry/chemistry-essential-ideas/atomic-and-atomic-mass-number">number</a> of metal items from your home or school. Some examples are listed below:
<ol style="list-style-type: lower-alpha;">
<li>
hair clips
</li>
<li>
safety pins
</li>
<li>
cooking pots
</li>
<li>
jewellery
</li>
<li>
scissors
</li>
<li>
cutlery (knives, forks, spoons)
</li>
</ol>
</li>
<li>
In groups of \(\text{3}\)–\(\text{4}\), combine your collection of metal objects.
</li>
<li>
What is the function of each of these objects?
</li>
<li>
Discuss why you think metal was used to make each object. You should consider the properties of metals when you answer this question.

Metals

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 arrangement of elements and learn about materials, mixtures, pure substances, and separation techniques, including chemical formulae and important concepts such as periods in the periodic table and chemical properties of groups.
