    關(guān)于原子結(jié)構(gòu) 光譜
    1.光最長的波長用來破裂 Cl2中的Cl-Cl鍵是495nm
    試計算Cl-Cl的最低能量.(怎么找最低能量?)
    2.氫原子的光譜 中特定的line和電子轉(zhuǎn)移從n=6到n=2有關(guān)
    試說明:
    在一樣的電子轉(zhuǎn)移的情況下(6-2) He+ 能量 大于 corresponding transition in H atom 氫原子
    (A certain line in the spectrum of atomic hydrogen is associated with the electronic transtition in the H aton from the sixth evergy level to the sexond energy level
    1.account for the observation that the amount of energy associated with the same electronic transition(n=6 to n=2)in the He+ ion is greater than that associated with the correspinding transition in the H atom)
    翻譯不太準(zhǔn)確 請能看懂的大師指點

    優(yōu)質(zhì)解答
    1)
    DeltaE=E(bonding)-E(antibonding)=E(photon)=hf=hc/lamda(wavelength)
    h:Planck constant
    c:speed of light
    2) Because E(n)=-RhZ^2/n^2
    for H atom Z=1,but for He+ Z=2.
    so for H,and DeltaE=Rh(1/4-1/36)
    but for He+,DeltaE=4Rh(1/4-1/36)
