The elements in which the last electron enters the d-orbital of the penultimate shell i.e.,(n-1)d-orbital where ‘n’ is the outermost shell, are called d-block elements.
Their general valence or outer electronic configuration is (n – 1) d1-10 ns 1-2
Explain the position of d-block elements in the periodic table.
