从化学及冶金中的实验现象归纳出原子态贵金属的化学稳定性是按周期表位置从左到右增强, 即RuRh>Pd>Ag, Os>Ir>Pt>Au, 两种顺序恰好相反。 金属态抗酸、 碱的腐蚀性能应为原子的化学稳定性与金属键强度的综合表现, 应重视区分原子态和金属态化学稳定性的差异, 并可从原子结构理论和金属键的价键理论作出解释。

The chemical stability of atom-state precious metals is according with the order of RuRh>Pd>Ag and Os>Ir>Pt>Au from the data of atomized-heats, melting points, and boiling points of precious metals, The differences in concepts of atom and metal state of precious metals were also given out, and the explanations for these were discussed from the atomic structure and metal bond theories.
