- And we can think about why -- essentially we have fluorine and now we're adding another electron. So you can picture that fluorine is going to get larger in this case And that would be true for all of the negatively charged ions.
我们可以想一想这是为什么-,本质上来讲我们现在给氟原子加上了,另外一个电子,因此大家可以想象在这种情况下氟将变大,而且这对于其它负离子也是成立的。
