So, this again, takes advantage of those great unique properties of transition metals, which we'll talk about in this course.
这同样也是利用了,过渡金属的独特性质,这个我们在以后的课程里也会讲到。
Water has some pretty unique properties, which we'll deal with a little bit later.
水有很多独特的性质,其中有许多我们到很晚才开始对它进行研究。
So, my final example is from Alan Davidson's lab, and Alan is an inorganic chemist -- he loved those transition metals and they're unique properties, and he designed this compound, it's called Cardiolite, Cardiolite and it's used in heart imaging.
最后一个例子是Alan,Davidson实验室,他是个无机化学家-,他喜欢研究过渡金属,和它们的奇特性质,他设计了这种化合物,叫做。
Why? Bundle of properties: mechanical strength, chemical inertness, ease of fabrication: that's not a unique solution.
为什么,属性的总和:,机械强度,化学惰性,易于制造,那不是独特的解决方法。
So, when the value of the average valence electron energy lies between 11 eV and 13 eV, we have these elements that are neither fish nor fowl, and you'll see in a little bit their unique electrical properties.
所以,当平均价电子能,在11eV到13eV之间时,这些元素介于金属和非金属之间,你们将进一步,看到它们独特的电性质。
