Chiari malformation In Chiari malformation surgery, doctors remove a small section of bone at the back of your skull to make room for part of your brain (cerebellum) and relieve pressure on your brainstem, cerebellum and spinal cord.
Europium is a ductile metal with a hardness similar to that of lead. It crystallizes in a body-centered cubic lattice. Some properties of europium are strongly influenced by its half-filled electron shell.Europium has the second lowest melting point and the lowest density of all lanthanides.uropium is a ductile metal with a hardness similar to that of lead.

Two things: First, a stationary electron does generate a weak magnetic field. It has a spin, and a corresponding magnetic dipole moment. But this field is extremely small. The coupling between this field and the orbital angular momentum of an electron is responsible for some subtle effects in atomic spectra, but for most purposes it's negligible.
