Question

关于原子结构 光谱 1.光最长的波长用来破裂 Cl2中的Cl-Cl键是495nm 试计算Cl-Cl的最低能量.（怎么找最

Answer 1

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)
