So, let's say we have an atomic number of 3, 3 that means we have 3 electrons, so we better hope to get our neutral atom that we have a charge of plus 3in the nucleus.

这也是很合理的，因为Z就是原子序数，假设原子序数是，那就有3个电子，那我们就希望,性原子有个带3个正电荷的原子核。

So similarly, as we now move up only one more atom in the table, 3 so to an atomic number of three or lithium, now we're going from six variables all the way to nine variables.

类似地就像我们现在,移动到周期表中仅仅多一个电子的情况，移动到一个原子数为，或者锂元素,现在我们从6个变量到了9个变量。
