Hydride gap:
The metals of 7th, 8th and 9th groups in the periodic table do not form hydrides and this region of periodic table is referred to as the hydride gap.[ - ] The metals of 7th, 8th and 9th groups in the periodic table do not form hydrides and this region of periodic table is referred to as the hydride gap.
Heavy water is used in certain types of nuclear reactors, where it acts as a neutron moderator to slow down neutrons so that they are more likely to react with the fissile uranium-235 than with uranium-238, which captures neutrons without fissioning. The CANDU reactor uses this design.
