WebThe concentration of deuterium relative to hydrogen is very very small. It's is much easier for a deuterium atom to come across a hydrogen atom and form HD. The probability of two D coming together to form D 2 is lower. This may be the cause of most deuterium not only on earth but the entire universe to be present as HD.
