Superheavy water

The physical properties of light water (H O), heavy water (D O) and superheavy water (T O) at room temperature (20°C) are listed in Table 20.14, while polynomial equations for calculating the density, viscosity, surface tension and vapor pressure of water at various temperature are provided in Table 20.15.

There are undoubtedly more elements on the way, as little by little the Periodic Table is extended into uncharted waters. And as this happens, we will learn about how these new elements behave. In 1997 an international team that included scientists from GSI, Berkeley, and Dubna was able to deduce that element 106 (seaborgium) has chemical properties similar to molybdenum and tungsten. In a sense this might have been expected, since seaborgium sits below these elements in the Periodic Table. But in fact the result was a surprise, because the chemical behaviour of the preceeding superheavy elements 104 and 105 is distorted by the effects of relativity on the electrons surrounding the immense nuclei.
