Ion 離子

離子是指原子或原子基團失去或得到一個或幾個電子而形成的帶電荷的個子。

Ion = When an Atom gain or lose an electron

我還是大推 Tyler 的影片….比我用寫的還清楚。Youtube 有翻譯的功能喔, 到設定Setting, 選字幕-自動翻譯-中文。就有中文字幕了

 

Ionic Bonding

Ionic bonding is the complete transfer of valence electron(s) between atoms. It is a type of chemical bond that generates two oppositely charged ions. In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion.

舉例來說,Sodium (Na) 有11個電子, Chlorine (Cl)有17個…

Na 的 Valence Number +1, Chlorine’s Valence Number is -1.

所以Na 會想盡辦法把他多出來的一個電子塞給別的原子, 而Cl 會想盡辦法從別的原子偷走一個電子。當這兩個原子撞在一起, 就會互相吸引。成為NaCl

Na 原本Protons 有11個, 電子11個..走了一個電子, 電子就變成10個。Na 就變成 Positive charged ion, 也叫做Cation 陽離子。

Cl 原本Protons 17個, 電子17個。現在偷了一個電子過來, 電子變成18。Cl 變成Negative charged Ion, 也叫做Anion. 負離子
