1·Professor Harrison, were you saying that the periodic table is predictive?
哈里森教授，你是在说周期表是可以预测的吗？
2·The structure of the periodic table appeared to limit the number of possible elements.
元素周期表的结构似乎限制了潜在元素的数量。
3·In fact, subsequent work has shown that in a periodic table, elements should not be ordered strictly by atomic mass.
事实上，后来的研究已经证明，在元素周期表中，元素不应该严格按照原子质量来排序。
4·Does that explain why it was missing in the periodic table?
这能解释为什么它在元素周期表中缺失了吗？
5·For example, tellurium comes before iodine in the periodic table, even though its atomic mass is slightly greater.
例如在元素周期表中，碲排在碘之前，尽管它的原子质量略大一些。
