And now we're asking you to look at krypton, so the atomic mass is 36. You can actually just grab that handout the second handout on the exam and look at the periodic table there. So, which of the following ions listed is isoelectronic with krypton?

现在我们请大家来看一下氪原子，它的原子量是，36，大家其实可以拿出这张讲义,第二份关于考试的讲义,看一下上面的周期表，那么，下列离子中，哪一个是与氪原子是等电子的？
