Yes, germanium does form isotopes. It has five stable isotopes: germanium-70, germanium-72, germanium-73, germanium-74, and germanium-76. Additionally, there are several unstable isotopes of germanium that have been produced in laboratories.
Natural germanium has only one radioactive isotope - germanium 76. 27 artificial radioisotopes of germanium are known.
The isotopes 252Cf and 251Cf.
92.66% of the germanium found in nature is not radioactive. 7.44% of germanium is 76Ge, which has a very long half life of 1.78 x 1021 years.
The most common isotope of uranium is uranium-238.
Each one has 32 protons, because that is the atomic number of germanium. The remaining nuclear mass is due to neutrons, of which there are 38, 40, 41, and 44 respectively from the lightest to the heaviest of these isotopes.
silicon and germanium
Germanium can form compounds with elements such as oxygen, sulfur, and chlorine. For example, germanium dioxide (GeO2) and germanium tetrachloride (GeCl4) are common compounds formed by combining germanium with oxygen and chlorine, respectively.
Germanium has five naturally occurring isotopes ranging in atomic mass number from 70 to 76. The number given in the periodic table is: 72,63
The ionic radius of germanium can vary depending on its oxidation state. However, for germanium in its most common oxidation state of +4, the ionic radius is approximately 0.53 nanometers.
