Answer» 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.
