CHEM:::CHEMICAL CELL & ELECTROLYSIS"

我想問.....
(sj BY0jaU
#q |+@'_z`^? delocatized electron同mobile ion分別係d咩黎....6U+_ i_jU

8x PM?5A8[ A@ 幾時用delocatized electron....幾時用mobile ion....2D}XD"O

(H+OLd/Sc/Z 佢地之間有乜分別呢.."p |*YR+p Mww \4]a)p

c7`2xq bG+f 就是這樣吧...謝"

牙糖. do you mean delocalized election?? electron is part of an atom, whereas an ion is like (Na+, K+, Cl-), an element with extra charges (could have MORE electrons or LESS electrons)9v)q:r6C:h`-TW%j4J
aq1`]Ms
does that kind of help?

actually, ion doesnt HAVE to be an element, just an example.

你有無睇過果舊6角形既圖啊= =??

if the electrons are not delocalized, gum mut current dou gone la!!}0@v4DyBlr$z

#f.K^2ct4B AYL like the electrons need to move in order to "carry a current"

redox既野.......我非常差@@

?YF({QX 不過可以答你既係......通常electron係圍住nucleus轉架.......唔可以自由活動,所以傳唔到電
Z1a \+W*` v6q$n2f
U'{P~H0dl5H@ 但好似pure metal咁........因為d  outermost electron唔係黐住nucleus,可以自由活動,可以傳電,所以就叫delocalized electron

@qq5S u%\~ 一般cation會黐住anion,當solid既時候就會唔傳電,因為郁唔到

xe Z~5GTn 但溶左入水之後,可以自由活動,可以傳電,所以就叫mobile ion
