&lt;p&gt;&lt;strong&gt;Ptbl&lt;/strong&gt; is a periodic table for the Linux desktop, built with GTK 4 and libadwaita. It works offline.&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;strong&gt;Browse&lt;/strong&gt; all 118 elements, coloured by category, with up to 40 properties per element on six tabs.&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;Search and filter&lt;/strong&gt;: find an element by symbol or name as you type, or highlight one category, such as the transition metals.&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;Colour by property&lt;/strong&gt;: turn the table into a heatmap of one of eight properties.&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;Trend charts&lt;/strong&gt;: plot atomic, covalent or van der Waals radius, or electron affinity, against atomic number.&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;Vegard&amp;rsquo;s law calculator&lt;/strong&gt;: estimate the lattice parameters, cell volume and density of an alloy from its composition, then open the structure in &lt;a href="../cview/"&gt;CView&lt;/a&gt; or export it as a CIF file.&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;Atomic and thermal properties come from a bundled snapshot of the &lt;a href="https://pubchem.ncbi.nlm.nih.gov/periodic-table/" target="_blank" rel="noopener"&gt;PubChem periodic table&lt;/a&gt;. Some crystal, electrical, magnetic and nuclear values come from earlier versions of Ptbl and haven&amp;rsquo;t yet been checked against current sources, so verify them before relying on them. Vegard&amp;rsquo;s-law results are quick estimates, not a substitute for a calculation or a measurement.&lt;/p&gt;
&lt;h2 id="quick-start"&gt;Quick Start&lt;/h2&gt;
&lt;p&gt;Ptbl needs Linux, Python 3.10 or newer, and GTK 4.12, libadwaita 1.5 and PyGObject from your distribution&amp;rsquo;s packages (on Fedora: &lt;code&gt;sudo dnf install gtk4 libadwaita python3-gobject&lt;/code&gt;).&lt;/p&gt;

&lt;/span&gt;&lt;/span&gt;&lt;/code&gt;&lt;/pre&gt;&lt;/div&gt;&lt;p&gt;On Debian, Ubuntu and Arch Linux, add &lt;code&gt;--break-system-packages&lt;/code&gt;. The &lt;a href="https://github.com/mavens-group/Ptbl#installation" target="_blank" rel="noopener"&gt;README&lt;/a&gt; covers every distribution, virtual environments and troubleshooting.&lt;/p&gt;</description></item></channel></rss>
