Other Chemical Properties
?
Stable metals are non radioactive metals and have zero valence electrons in the outer shell.Chemical Stability, 
?
Corrosion is a process which converts refined metals to their more stable forms, for example, its oxide and hydroxide. This process of metals getting corroded is a gradual destruction of metals by chemical reactions.Corrosion, 
?
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

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   
?
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   
Element Family
?
Total 15 metals are included in Lanthanide series from Lanthanum to Lutetium. Lanthanide series is located under f and d block of the periodic table.Lanthanide   
?
What is Transition Metal? All transition metals are placed under the d-block from group number 3 to 12. Transition metals show characteristics like malleability, ductility and are good conductor of electricity.Transition Metal

Crystal Structure
?
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)   
?
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)
