You can see the hydrogens if you have enough resolution (below 1A). These days you start to see such good resolutions pretty often.

- ta988 4y agoHere are two articles supporting my point as you don't seem to believe it. I also recommend you go look at PDB and select structures below 1A so you can see for yourself. https://bmcresnotes.biomedcentral.com/articles/10.1186/1756-0500-6-30 https://bmcresnotes.biomedcentral.com/articles/10.1186/1756-... https://www.science.org/doi/10.1126/sciadv.1600192 https://www.science.org/doi/10.1126/sciadv.1600192 """ Textbooks and teaching classes still emphasize that hydrogen atoms cannot be located with x-rays close to heavy elements; instead, neutron diffraction is needed. We show that, contrary to widespread expectation, hydrogen atoms can be located very accurately using x-ray diffraction, yielding bond lengths involving hydrogen atoms (A–H) that are in agreement with results from neutron diffraction mostly within a single standard deviation"""
