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,

?
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,

?
Ductility of metals defines their ability to deform under tensile stress; this is often characterized by the metals ability to be stretched into a wire.Ductile, 
?
Malleability of metals defines their ability to deform under compressive stress; this is often characterized by the metals ability to form a thin sheet by hammering or rolling.Malleable, 
?
Weldability of metals defines their ability to be welded.This property of metals also known as joinability.Weldable

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
