周期表中0类元素包括氦 He、氖 Ne、氩Ar、氪 Kr、氙 Xe 和氡 Rn 等六种元素。过去一直由于其最外层电子层呈稳定结构,从而确信它们的性质不活泼,不起化学反应,并称之曰惰性气体。这种形而上学的观点束缚了人们的思想,阻碍了人们对0类元素的深入研究。此种偏见,直到1962年 Bartlett 报导了制成稳定 The Periodic Table 0 elements include helium He, neon Ne, argon Ar, krypton Kr, xenon Xe and radon Rn six elements. In the past, the outermost electron layers were stable, so they were sure that their properties were not active and could not react chemically. They said it was an inert gas. This metaphysical view constrains people’s thinking and hinders people’s in-depth study of category 0 elements. This bias until Bartlett reported 1962 made stable
