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,
?
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,

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 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
?
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

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)
