प्रश्न
Give a reason for the following:
Actinoids show irregularities in their electronic configurations.
Advertisements
उत्तर १
Actinoids show irregularities in their electronic configurations because the energy differences between 5f, 6d and 7s subshells are very small; hence, an electron can be occupied in any of the subshells. They have the electronic configuration of 7s2 with variation of occupancy in 5f and 6d orbitals.
उत्तर २
Actinoids show irregularities in their electronic configuration are related to their stabilities of the f0,f7, and f14 occupancies of the 5f orbital.
