		<summary type="html">&lt;p&gt;Created page with &amp;quot;Down quarks &amp;lt;span style=&amp;quot;font-size: 13.28px;&amp;quot;&amp;gt;have a -1/3 charge&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size: 13.28px;&amp;quot;&amp;gt; and are fermions, which means they have a 1/2 spin.&amp;lt;/span&amp;gt;&amp;lt;spa...&amp;quot;&lt;/p&gt;
&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;Down quarks&amp;amp;nbsp;&amp;lt;span style=&amp;quot;font-size: 13.28px;&amp;quot;&amp;gt;have a -1/3 charge&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size: 13.28px;&amp;quot;&amp;gt;&amp;amp;nbsp;and are fermions, which means they have a 1/2 spin.&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size: 13.28px;&amp;quot;&amp;gt;The anti-down quark has a charge of +1/3 and they both have a strangeness of 0.&amp;lt;/span&amp;gt; &lt;br /&gt;
&lt;br /&gt;
&amp;lt;span style=&amp;quot;font-size: 13.28px;&amp;quot;&amp;gt;When this flavour of quarks is combined with up quarks, protons and neutrons can be formed. If one up quark and two down quarks are combined, a neutron is created. If a particle has two up quarks and one down quark, it is a proton. &amp;lt;/span&amp;gt; &lt;br /&gt;
&lt;br /&gt;
&amp;lt;span style=&amp;quot;font-size: 13.28px;&amp;quot;&amp;gt;The charges of atom nuclei are determined by the charges of their quarks. For instance a proton has two up (+2/3) and one down (-1/3), leaving it with an overall charge of +1.&amp;amp;nbsp;&amp;lt;/span&amp;gt; &lt;br /&gt;
&lt;br /&gt;
Up and down quarks are the least heavy of the quark flavours, meaning that after the process of particle decay, they can be formed from other flavours.&lt;/div&gt;</summary>
