The atoms bond because there is a strong enough attraction in both directions and room for the electrons in the outer energy level of the atoms. When two hydrogen atoms and an oxygen atom get close ...

A new calculation of the electron's self-energy improves determination of fundamental constantsIt came when the one electron of the hydrogen atom transitioned from the 2P 1/2 energy level to the 2S 1/2 level. (The leftmost number is the principal quantum number, much like the discrete but ...
One is the spectroscopy of the internal structure, the internal energy levels of the anti-hydrogen atom to compare them ... antihydrogen atoms can make the spectrum narrower," said Hangst.
MANY examples of changes in ultra-violet absorption spectra attributable to hydrogen bonding have been ... of lone-pair electrons on an oxygen atom acting as a proton acceptor 2.
