Block
?
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 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 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
  
?
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
?
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 cubic (or isometric) crystal system is a crystal system where the unit cell is in the shape of a cube. This is one of the most common and simplest shapes found in crystals and minerals.Face Centered Cubic (FCC)
