WebDec 23, 2015 · Relativistic contraction occurs along period 7 as it does in period 6, but the maximum occurs at eka-mercury and not below gold as expected. It remains to be seen whether element 112 exhibits the effects of relativity. So perhaps the jury is still out on whether relativity will undermine Mendeleev’s periodicity as new elements are added. WebFeb 8, 2024 · So chemistry quickly incorporated these theories into what is called “relativistic quantum chemistry”. In this branch of chemistry, one of the most important things is the relativistic movement.
