Question

what are d block elements? what makes them being named as transition element.​

Answer 1

Answer:

D - Block element are those element whose one or more outermost electron in d - orbitals .D - orbital are also called D - generate orbital because the energy of all 5 sub - orbital is same 2Dq each and 10 Dq of all 5 orbital .

D- orbital are called transition element because of partially filled d - orbitals .
