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   
?
Anti-corrosion metals have the protection on their surfaces which protect them from corroding in corrosive environments.Anti Corrosion,

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

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 actinide series, from Actinium to Lawrencium. Actinide series is located under f and d block of the periodic table.Actinide   
?
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)   
?
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)
