1st orbital in He+

Postby Yinhan_Liu_1D » Tue Oct 18, 2016 3:35 pm

In the book p37, it asks "How would you expect a 1st-orbital in He+ to differ from the sam orbital in H?"

They have the same wavefunction, right?

I can't figure it out. It would be great if you could help me.

Thanks a lot;)

The reason is actually because the nucleus of He+ has a 2+ charge while the H nucleus has a 1+ charge. This makes it so that the He+ nucleus attracts the electrons more strongly so structure-wise, the 1s orbital is a lot closer in He+ compared to H. I hope this helps.
