hi i am working on trying to derive KE (or Etrans)=3/2nRT so i know these steps that ___________ pV= nRT and pV= 1/3 NmV2 and combining them, we get nRT= 1/3Nmv2 also, we know that for translational motion, KE= 1/2Nmv2 ______ i don't know how 2/3 (1 /2 Nm...

i got it (thanks for the input) i worked out the effective nuclear charge for both states and found out that for a 4s1 electron, Z* was 2 and for the 3d1, it was 1 thus, the 3d1 electron is shielded more than the 4s1 electron..so it could be said that the...
