Question
Sir,the electronc configuration of uranium should be [Rn]7s^25f^4 but it is [Rn]5f^3 6d^1 7s^2. How can 6d orbital (which is higher in energy ) be filled before completing 5f orbital (which is lower in energy)?

Exchang of energy leads to stability thus in order to gain stability it changes its energy thus in its configuration 6d is filled be4 5f .
