Think xyz axis in space.
Assume there are two Hydrogen atoms on the x axis.
Assume they are heading toward each other along the x axis.
Then what do you predict will happen?
A Hydrogen molecule will necessarily be formed or not?
How about assuming the initial states of the two Hydrogen atoms to be both in 1S state?
Or rather how about assuming them to be 2Py and 2Pz states each?
I think the latter case seems more favorable for forming a Hydrogen bonding.
Because the electrical charge distribution might form a net attraction between all of the participant electrons and protons upon collision.
And if the bonding were to be formed, then after bonding are the protons oscillating?
After the bonding, are the electron clouds ocsillating too?
How do you muse?
P.S. If some net charge acceleration occurs upon the bondong process, then do you think that some electromagnetic radition accompanies?
