Abstract

Flerovium (Fl, element 114) is the heaviest element chemically studied so far. To date, its interaction with gold was investigated in two gas-solid chromatography experiments, which reported two different types of interaction, however, each based on the level of a few registered atoms only. Whereas noble-gas-like properties were suggested from the first experiment, the second one pointed at a volatile-metal-like character. Here, we present further experimental data on adsorption studies of Fl on silicon oxide and gold surfaces, accounting for the inhomogeneous nature of the surface, as it was used in the experiment and analyzed as part of the reported studies. We confirm that Fl is highly volatile and the least reactive member of group 14. Our experimental observations suggest that Fl exhibits lower reactivity towards Au than the volatile metal Hg, but higher reactivity than the noble gas Rn.

摘要

鈇（Fl，第114号元素）是迄今为止进行过化学研究的最重元素。到目前为止，在两项气固色谱实验中研究了它与金的相互作用，这两项实验报告了两种不同类型的相互作用，然而，每种相互作用都仅基于少数几个已记录原子的水平。虽然第一个实验表明其具有类似稀有气体的性质，但第二个实验则表明其具有类似挥发性金属的特征。在此，我们展示了关于鈇在氧化硅和金表面吸附研究的进一步实验数据，考虑到实验中所使用表面的不均匀性质，并作为所报告研究的一部分进行了分析。我们证实，鈇具有高度挥发性，是第14族中反应活性最低的元素。我们的实验观察表明，鈇对金的反应活性低于挥发性金属汞，但高于稀有气体氡。
