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, 
?
Solubility is a chemical property referring to the ability for a given substance, the solute, to dissolve in a solvent.Solubility   
?
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, 
?
Flammable metals have ability to burn or ignite, causing fire or combustion.Flammable,

The p-block is on the right side of the periodic table and includes elements from the six columns beginning with column 13 and ending with column 18. Helium, though being in the top of group 18, is not included in the p-block.p 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
?
All post transition metals are placed in group number 13, 14 and 15 of periodic table. In fact, they are located between Transition Metals and Metalloids. Post transition metals have very poor mechanical properties.Post-​Transition   
?
Total 15 metals are included in Lanthanide series from Lanthanum to Lutetium. Lanthanide series is located under f and d block of the periodic table.Lanthanide

Crystal Structure
?
The tetragonal crystal structure occur as a result of stretching a cubic lattice along one of its lattice vectors due to which cube becomes a rectangular prism with a square shape at base.Tetragonal (TETR)   
?
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)
