该条涉及为改进目前标准的18列元素周期表而提出的各种建议。我们首先回顾元素周期表的8列、18列和32列格式。然后是对一个可能的、尽管相当不切实际的50列的表的审查，以及如何利用它来考虑皮耶克在超重元素领域预测的元素周期表的变化。审查的其他主题包括尝试推导马德隆规则，以及分析该规则实际提供了什么。最后，在科学哲学家最近的工作中讨论了“最佳”元素周期表的概念，他们研究了一般分类的性质，以及自然种类的概念。这篇文章采取了一种毫无歉意的哲学方法，而不是专注于有关元素的具体数据。尽管如此，也研究了元素周期表的一些实用问题和教育方面。本文是《门捷列夫与元素周期表》专题的一部分。
The article concerns various proposals that have been made with the aim of improving the currently standard 18-column periodic table. We begin with a review of 8-, 18- and 32-column formats of the periodic table. This is followed by an examination of a possible, although rather impractical, 50-column table and how it could be used to consider the changes to the periodic table that have been predicted by Pyykkö in the domain of superheavy elements. Other topics reviewed include attempts to derive the Madelung rule as well as an analysis of what this rule actually provides. Finally, the notion of an ‘optimal’ periodic table is discussed in the context of recent work by philosophers of science who have examined the nature of classifications in general, as well as the notion of natural kinds. The article takes an unapologetically philosophical approach rather than focusing on specific data concerning the elements. Nevertheless, some pragmatic issues and educational aspects of the periodic table are also examined. This article is part of the theme issue ‘Mendeleev and the periodic table’.
