Hafniums large neutron capture cross-section makes it a good material for neutron absorption in control rods in nuclear power plants, but at the same time requires that it be removed from the neutron-transparent corrosion-resistant zirconium alloys used in nuclear reactors. J/ (kg C). Sodium is an alkali metal, being in group 1 of the periodic table, because it has a single electron in its outer shell that it readily donates, creating a positively charged atomthe Na+ cation. Heat capacity is anextensive propertyof matter, meaning it is proportional to the size of the system.
