Use molecular orbital theory to explain why Be, molecule does not exist. |
|
Answer» Solution :The atomic no. (z) of Be is 4. This means that S ELECTRONS are to be FILLED in the M.O. of `Be_(2)` The configuration is : `sigma1s^(2)sigma**1s^(2)sigma2s^(2)sigma**2s^(2)`: `B.O.=1/2[N_(b)-N_(a)]=1/2[4-4]=0` As bond order of `Be_(2)` is zero the MOLECULE of `Be_(2)` does not exit. |
