Classification of Elements : d-block -

  • The d-block is in between s and p blocks. In these elements, their last electron enters into any of the d-orbitals. These elements are also known as transition elements as their properties are in between s and p-block elements. 

  • The general electronic configuration of d-block elements is (n-1)d1-10ns1-2.

  • These elements are in between 2-13 group in the periodic table.

-

The d-block elements are those elements whose last electron enters into the d-orbital. The general electronic configuration of the elements belong to d-block elements is:   (n-1)d^{1-10} ns^{1-2}

Therefore, Option(2) is correct
