?
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, 
?
Solubility is a chemical property referring to the ability for a given substance, the solute, to dissolve in a solvent.Solubility

Block
?
The d-block is on the middle of the periodic table and includes elements from columns 3 through 12. These elements are also known as the transition metals because they show a transitivity in their properties i.e. they show a trend in their properties.d block
  
?
The p-block is on the right side of the periodic table and includes elements from the six columns beginning with column 13 and ending with column 18. Helium, though being in the top of group 18, is not included in the p-block.p block

Crystal Structure
?
BCC is a basis type of cubic crystal structure. In crystallography, the cubic crystals structure is a crystal system where the unit cell has a cube shaped structure. This is one of the simplest crystal structure found in crystals of metal.Body Centered Cubic (BCC)
  
?
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)
