这一点显得颇为神秘,因为和铅特性差不大多的锡,无法用来做电池。
Metallic tin is not electropositive enough compared with the electronegativity of its oxide todeliver a useful potential difference.
比起铅来,金属锡的电正性没有二氧化锡的电负性强,所以无法产生可用的电位差。
This is partly explained because the bigger an atom is, the more weakly its outer electronsare bound to it and hence the further those electrons are from the nucleus.
原子越大,其外层电子受原子束缚力越弱,这是解释铅和锡两者差别的一部分原因。
In all groups of chemically similar elements the heaviest are the most electropositive.
在化学性质相似的同族元素中,质量越重带的正电越强。
However, this is not enough to account for the difference between lead and tin.
然而这依然不能充分说明铅和锡的差别。
To put it bluntly, classical chemical theory predicts that cars should not start in the morning.
直截了当地说, 古典化学理论预言了早上要离家上班汽车是发不动的。
Which is where Einstein comes in.
那爱因斯坦怎么被扯进来了,
