positive electron affinity

基本解釋

So do you think noble gases would have a high positive electron affinity, a low positive, or negative electron affinity?
那么，你認為稀有氣體的電子親和能，應該是一個高的正值，一個低的正值，還是一個負值？
So, for example, for the chlorine case, we would say that the electron affinity for chlorine is actually positive 349 kilojoules per mole.
比如，以氯為例，我們可以說氯的電子親和能，應該等于正的，349，千焦每摩爾。
One major difference between electron affinity and ionization energy is that when we talked about ionization energy, remember ionization energy always has to be positive.
電子親和能,與電離能之間最大的不同就在于,當我們提到電離能的時候，記得電離能總是正的。

So, basically any time we have a really high positive number of electron affinity, it means that that atom or ion really wants to gain another electron, and it will be very stable and happy if it does so.
因此，基本上無論什么時候,只要我們有一個很大的正的電子親和能，這就意味著這個原子,或離子非常希望得到一個電子，如果它得到了，會變得更穩(wěn)定更開心。
