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, 
?
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,

Solubility is a chemical property referring to the ability for a given substance, the solute, to dissolve in a solvent.Solubility

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   
?
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
?
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   
?
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
?
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)   
?
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)
