Heavy Water

Heavy water is the common name for deuteriom oxide (D2O). It is a liquid denser than water (d=1.106 g/cm3). It is used in nuclear reactors as a moderator to stop neutron movement. 

Deuterium is an isotope of Hydrogen, having one proton and one neutron. It represents the 0.015% of all Hydrogen atoms.

Hydrogen Bond

No, it’s not about 007 or anything like that. Hydrogen bond is a type of intermolecular (and sometimes intramolecular) bond that forms between an hydrogen and an electronegative atom (Nitrogen, Oxigen and Flourine).

An example of intermolecular hydrogen bonding in aself-assembled dimer complex reported by Meijer and coworkers. The hydrogen bonds are the dotted lines. (Wikipedia).

Even though it might not be a very strong type of bonding it is extremely crucial for life as we know it. It is responsible for water’s physical properties and it is even in our DNA.

I am a very huge fan of Martin Poliakoff and all of the “periodic table of videos” crew. So here it is their video on Hydrogen. Enjoy, learn, share!
