The element with the electronic configuration `[Ze]^(54) 4f^(14)5d^(1)6S^(2)` is aA. representative elementB. d-block elementC. lanthanoidD. actinoid |
|
Answer» After achieving `4f^(14),5d^(0),6s^(2)` configuration , the next electron goes to `5d` and this is the case of `Lu(Z=71)` which is the last element of lanthanoid series Therefore , (C ) option is correct |
