Actinide series is arises due to

Answer»

stability of 5f-orbitals
stability of 7s-orbitals
stability of 6d-orbitals
equal stability of 6d and 5f-orbitals

Solution :We know that, in `7 ^(th)` row after 7s-orbitals the next electrons enters into 6d-orbitals. At this STAGE 6d-orbitals stop its spliting and 5f-orbitals, split into 7 orbitals, and BECOME lower energy than, 6d-orbitals. Hence 5f-orbitals are progressively filled and 14 NEW ELEMENTS are ADDED called as actinides.
