一、引言氦、氖、氩、氪、氙和氡六种稀有气体是上一世纪末到本世纪初发现的。由于它们的性质不活泼、具有八隅体的稳定电子结构,以及在1962年以前一直没有发现它们同其他元素生成的化合物,所以习惯上把它们叫做“惰性气体”。一般化学家在他们的工作中,特别是化学教师在他们的教学工作中,就常常把这些稀有气体 I. INTRODUCTION The six rare gases of helium, neon, argon, krypton, xenon and radon were discovered from the end of the previous century to the beginning of this century. They are customarily called “noble gases,” because of their inactive nature, their stable electronic structure with octants, and the compounds they did not find themselves with other elements until 1962. General chemists in their work, especially chemistry teachers in their teaching, often these rare gases
