We cover its origins and evolution, from Dmitri Mendeleev’s groundbreaking arrangement to the modern periodic table’s organisation, its influence and role in science and culture, the discovery of new elements and element scarcity.</p> <p> </p></div></div></div> <div id="top" class="area"> <div class="grid"> <div class="twoColumns"> <div class="columnContainer"> <div class="column columnOne"> <div id="history_116190" class="spinBlock colour1 hastitle spin-section-heading"><div class="sleeve"><div class="sectionhead"><h2>History</h2></div><div class="spinLayout half onecol left item-first item-last hasPicture"><div class="sleeve"><p class="picture"><a href="https://www.chemistryworld.com/features/the-father-of-the-periodic-table/3009828.article" class="image layoutIcon pictureLayout"><img alt="A picture of Mendeleev with his 1869 periodic table" class="lazyloaded" loading="eager" sizes="(max-width:479px) 100vw, (max-width:767px) 50vw, (max-width:1023px) 300px, 274px" src="https://d2cbg94ubxgsnp.cloudfront.net/Pictures/173x115/3/4/9/140349_Mendeleev-3by2.jpg" srcset="https://d2cbg94ubxgsnp.cloudfront.net/Pictures/173x115/3/4/9/140349_Mendeleev-3by2.jpg 173w,https://d2cbg94ubxgsnp.cloudfront.net/Pictures/300x200/3/4/9/140349_Mendeleev-3by2.jpg 300w,https://d2cbg94ubxgsnp.cloudfront.net/Pictures/460x307/3/4/9/140349_Mendeleev-3by2.jpg 460w" width="173" height="115" /></a></p><div class="subSleeve"><h2><a href="https://www.chemistryworld.com/features/the-father-of-the-periodic-table/3009828.article">The father of the periodic table</a></h2><p class="meta"><span class="author">By <a rel="author" href="https://www.chemistryworld.com/mike-sutton/1780.bio">Mike Sutton</a></span></p><p class="intro">Mike Sutton looks at how Mendeleev’s patience revealed periodicity in the elements</p></div></div></div></div></div><div id="history_116200" class="spinBlock colour1 hasnotitle spin-1024-show-intro spin-show-separator-lines"><div class="sleeve"><div class="spinLayout thumb onecol left item-first"><div class="sleeve"><div class="subSleeve"><h2><a href="https://www.chemistryworld.com/features/primo-levi-and-the-other-periodic-table/3010512.article">Primo Levi and the other periodic table</a></h2><p class="meta"><span class="author">By <a rel="author" href="https://www.chemistryworld.com/philip-ball/1873.bio">Philip Ball</a></span></p><p class="intro">Author and chemist Primo Levi was born 100 years ago this July.
