Other Chemical Properties
?
Ionization is the process by which an atom or a molecule acquires a negative or positive charge by gaining or losing electrons to form ions, often in conjunction with other chemical changes.Ionization, 
?
Radioactive metals emit particles and radiation from their nuclei. This process comes in the picture because their nuclei experience the intense conflict between two strong forces. This metal also have radioactive isotopes.Radioactive Isotopes,

Crystal Structure
?
Rhombohedral crystal lattice structure comes under trigonal crystal structure. The Rhombohedral crystal structure is a term associated trigonal crystal structure with the rhombohedral lattice.Rhombohedral (RHO)   
?
Orthorhombic lattices occur due to stretching a cubic lattice along two of its orthogonal sides. It gets result in a rectangular prism with a rectangular at base. These 3 bases intersect each other at 90°.Orthorhombic (ORTH)
