What about the entire periodic table? That exercise is trickier because you have to arrange the data into the familiar format based on group and period, which requires some fancy coding.

这个练习需要更多技巧，因为要按照分组和周期将数据排列成常见的格式，所以需要某些具有想像力的代码，不能简单地将各部分放在固定的位置。

Noble gas (or inert gas) : Any of the six chemical elements that make up the rightmost group of the periodic table as usually arranged: helium, neon, argon, krypton, xenon, and radon.

稀有气体(亦称惰性气体)：通常排列在周期律中最右边一族的六种化学元素：氦、氖、氩、氪、氙和氡。

So if we consider lithium, potassium, and sodium, they're all together in the same group on the periodic table, knowing what we do about biology we can immediately think of sodium and potassium, or even just knowing what you know about table salt, for example, that these are two elements that we find, and particularly in the ion form in very high concentrations in our body.

我们来考虑一下锂，钾和钠，它们都在周期表中的同一族里，想要知道我们将元素周期律,用到生物学会怎么样，我们首先想到的就是钠和钾，甚至只需要知道食盐，我们发现它们是以很高浓度的离子形式,存在于我们体内的两种元素。
