Which of the following statement is wrong for the d-block elements?A. General electronic configuration for them is `(n-1)d^(1-10)ns^(0-2)`B. They generally exhibit variable valency .C. Last electron enters in `(n-1)d` subshell in them.D. They are placed from third period to sixth period in modern peridic table. |

Answer» Correct Answer - D Transition elements start from 4th period as they have valence shell configuration `(n-1)d^(1-10)ns^(1-2)`. So minimum possible value of `n` is `4`. |
