Other Chemical Properties
?
Stable metals are non radioactive metals and have zero valence electrons in the outer shell.Chemical Stability, 
?
Anti-corrosion metals have the protection on their surfaces which protect them from corroding in corrosive environments.Anti Corrosion, 
?
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
  
?
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,

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 s-block is on the left side of the periodic table that includes elements from the first two columns, the alkali metals (group 1) and alkaline earth metals (group 2), plus helium.s 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
  
?
All alkali metals are placed under group number 1 and s-block of periodic table. These metals are highly reactive and are found in ores of other metals and minerals. Alkali metals can be easily distinguished from others as these metals have only 1 electronAlkali
