Stable metals are non radioactive metals and have zero valence electrons in the outer shell.Chemical Stability, 
?
Flammable metals have ability to burn or ignite, causing fire or combustion.Flammable, 
?
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
?
The hexagonal crystal system consists of the 7 point groups such that all their space groups have the hexagonal lattice as underlying lattice. The hexagonal crystal family consists of the 12 point groups such that at least one of their space groups has theHexagonal Close Packed (HCP)   
?
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)
