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

Crystal Structure
?
Orthorhombic lattices occur due to stretching a cubic lattice along two of its orthogonal sides. It gets result in a rectangular prism with a rectangular at base. These 3 bases intersect each other at 90°.Orthorhombic (ORTH)
  
?
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)
