有几个factor不会解释
What factors are important in determining the following?
(a)Carbon only give monocarbonates, but silcon gives a huge number of polymeric
silicates.
(b) The[Re2X8]^2- ions are in eclipsed conformations, but most of the [Os2X8]^2-
ions in staggered conformation.
(c) Oxygen forms no chains longer than three, but the allotropes of both sulfur
& selenium are known in which helical chains are present.
(d) The chemical reactivity increases in order of Ne<Ar<Kr<Xe
(e) The chemical reactivity increases in order of Au<Ag<Cu
a、b很简单，一个是因为碳有pi键，一个是因为铼有delta键
c、d、e就不会解释了
c可以说是因为阴电性的关系吗？e可以说是因为还原电位的关系吗？
还有劳各位先进了....
