positive electron affinity

常見例句

So do you think noble gases would have a high positive electron affinity, a low positive, or negative electron affinity?
那么，你認(rèn)為稀有氣體的電子親和能，應(yīng)該是一個(gè)高的正值，一個(gè)低的正值，還是一個(gè)負(fù)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(yīng)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(dāng)我們提到電離能的時(shí)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(shí)候,只要我們有一個(gè)很大的正的電子親和能，這就意味著這個(gè)原子,或離子非常希望得到一個(gè)電子，如果它得到了，會(huì)變得更穩(wěn)定更開心。
