[化學] 兩題化學
1.What is the probability of finding a particle in a one-dimension box in
energy level n=4 between x=L/4 and x=L/2?
答案：25%
(有夠慘的我不知道他在問什麼是哪章節的啊Q_Q)
2.How many electrons in an atom can have the quantum numbers n=3,l=1?
答案是6
我答案寫18
查講義也是寫18
只是單純的答案錯誤還是他其實是在問n=3那層可以放多少電子?
看起來是不太像拉...
3.when Np undergoes beta emission,what are the product?
(Np質量數238質子數93)
答案是 Pu 質量數238 質子數94
真弔詭阿 beta emission 應該是質子數會減一吧@@
看一下質子數減一的答案有兩個還長的一模一樣= =
此為台大98C第20題
4.台大C卷第11題...厄那個Cr這樣子是要怎麼...

如果不是我太愚笨的話...我想只有20題的話有兩題出錯好像有點兒誇張
如果是我太愚笨搞不清楚其中奧義的話懇求大家不吝賜教=_=
(原來是ㄌ一ㄣˋ吝XD)
