d-Block elements:

  • d-Block contains elements from group 3 to group 12.
  • It is present in the middle of the modern periodic table.
  • They are also known as transition elements.
  • The last electron in the d-block elements enters in d orbital.
  • General outer electronic configuration of d-block elements is ns0-2 (n-1)d1-10.
  • e.g. Cu, Zn, Cr, Ti, V, etc.

f-Block elements:

  • f-Block contains elements of lanthanide and actinide series.
  • f-block elements are present below the modern periodic table as two separate rows.
  • They are also known as inner transition elements.
  • The last electron in the f-block elements enters in f orbital.
  • General outer electronic configuration of f-block elements is ns2 (n-1) d0-1 (n - 2) f114.
  • e.g. Ce, Pr, Nd Th, U, Np, etc.

The area of the upper face of a rectangular block is 0.5 m × 0.5 m and the lower face is fixed. The height of the block is 1 cm.

Given: A = 0.5 m × 0.5 m = 0.25 m2, h = 1 cm = 10-2m, x = 0.015 mm = 15 × 10-6m n = 4.5 × 1010 N/m2 To find: Strain (θ). Shearing...

Why elements of group 1 and group 2 are known as s-block elements?

The subshell in which the last electron enters decides the block to which an element belongs. In group 1 and group 2 elements, the last electron is filled in the s...

Comment on the chemical reactivity of d-block and f-block elements.

d-block (transition) elements and f-block (inner transition) elements exhibit very small change in atomic radii. Therefore, the transition and inner transition elements belonging to the individual series have similar chemical properties. Their...
