The d-and f-Block Elements POINTS TO BE REMEMBERED: --- The elements of periodic table belonging to group 3 to 12 are known as d-Block elements. The general electronic configuration of these elements is (n -1)d1-10 ns 1-2 d- Block elements are collectively known as Transition Elements because properties of these elements vary in between s-Block and p-Block elements. A transition element should have partially filled (n-1) d orbital. Group 12 elements i.e. Zn‚ Cd‚ Hg have
