Ytterbium has a bright silvery lustre, is soft, malleable, and quite ductile.    Noble Gases Increasing the pressure on an material (especially for liquids or gases) decreases the volume of the object and thus increases its density via the atomic number density. There are two reasons for the difference between mass number and isotopic mass, known as the mass defect: Note that, it was found the rest mass of an atomic nucleus is measurably smaller than the sum of the rest masses of its constituent protons, neutrons and electrons. Seven naturally occurring isotopes of ytterbium are known ranging from mass numbers 168 to 176. The naturally occurring ytterbium is a mixture of seven stable isotopes with mass numbers 168, 170 to 174 and 176. It is a white silvery, soft, ductile and rare earth metal. The density of a material varies with temperature and pressure. The size and mass of atoms are so small that the use of normal measuring units, while possible, is often inconvenient. The density of Hassium results from its high atomic weight and from the significant decrease in ionic radii of the elements in the lanthanide series, known as lanthanide and actinide contraction. Ytterbium also has 12 meta states, with the most stable being 169m Yb (t1/2 46 seconds).
