Other Chemical Properties
?
Stable metals are non radioactive metals and have zero valence electrons in the outer shell.Chemical Stability, 
?
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

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
  
?
The f-block is in the center-left of a 32-column periodic table but in the footnoted appendage of 18-column tables. These elements are not generally considered as part of any group. They are often called inner transition metals.f block
  

Element Family
?
All post transition metals are placed in group number 13, 14 and 15 of periodic table. In fact, they are located between Transition Metals and Metalloids. Post transition metals have very poor mechanical properties.Post-​Transition

Crystal Structure
?
In crystallography, the cubic (or isometric) crystal system is a crystal system where the unit cell is in the shape of a cube. This is one of the most common and simplest shapes found in crystals and minerals.Face Centered Cubic (FCC)
  
?
In crystallography, the hexagonal crystal structure and its double hexagonal crystal structure is one of the 7 crystal structure, The hexagonal lattice system consists of just one Bravais lattice type: the hexagonal shape.Double Hexagonal Close Packed (DHCP)
