※ 引述《appleM (天空不要為我掉眼淚)》之銘言： : 我還是有點弄不懂 "The particle in a box" : 像是下面的兩個題目我不太清楚在問什麼 : 希望有人可以告訴我 : For a particle in a cubic box, how many degenerate energy levels have : energy equal to 14h^2/8mL, in which L s the lenth of the cubic box. : (a)1 (b)2 (c)6 (d)8 (e)12 En=(nx^2+ny^2+nz^2)h^2/8mL^2 nx,ny,nz 可以是(1,2,3) 再去排列組合一下有6個選c : (a)Discuss what happens to the energy levels for an eletron trapped in a : one-dimensional box as the length of the box increases. 能量會降低根據En=n^2h^2/8mL^2 L變大En會下降 : (b)Which has the lowest(ground-state) energy, an eletron trapped in a one- : dimensional box of the length 10^(-5) or one with length 10^(-10)? 直接帶進去上面那個En的公式基態的話n代1 所以說10^-5的基態能量會比較小 : ------------------- : 另外還有一題我不太清楚題意 : What is the maximum number of electron in an atom that can have the : quantum number of n=3, l=2? : n=3, l=2 指的是 3d軌域 : 題目的意思是說3d軌愈能容納多少電子嗎? (10個) : 還是說有3d軌域的原子總共可以容納多少電子? (1s2s2p3s3p4s3d, 30個) 我覺得應該是total吧 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 59.104.201.224
