WebA discussion of He allotropes is presented in which it is noted that designations such as Re I, Re II, He/sup 3/, and He/sup 4/ are already in use. It is proposed that the allotropes of … WebThese allotropes, which are different structural modifications or forms of an element, have very similar internal energies but significantly varying densities and crystal structures. This makes plutonium very sensitive to changes in temperature, pressure, or chemistry, and allows for dramatic volume changes following phase transitions from one allotropic form …
