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 alkaline earth metals are placed under group number 2 and s-block of periodic table. These metals are somewhat reactive at standard conditions. Alkaline earth metals appear shiny, silvery-white and are found in the earth’s crust.Alkaline Earth

Crystal Structure
?
Rhombohedral crystal lattice structure comes under trigonal crystal structure. The Rhombohedral crystal structure is a term associated trigonal crystal structure with the rhombohedral lattice.Rhombohedral (RHO)   
?
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)
