Which of the following statements is wrong for the transition elements...
Transition elements starts from 4th period as they have valence shell configuration (n – 1)d1 - 10 ns0–2. Thus for n = 3, there is no d-orbital available.

Understanding Transition Elements
The transition elements, also known as transition metals, are a group of metals found in the d-block of the periodic table. Let's analyze the statements to identify the incorrect one.
Statement A: Transition elements are placed from 3rd to 6th period.
- This statement is incorrect because transition elements actually span from the 3rd period (Scandium, atomic number 21) to the 6th period (Zinc, atomic number 30) and continue into the 4th (Yttrium, atomic number 39) and 5th periods (Lanthanides). Therefore, they are not confined to only the 3rd to 6th periods.
Statement B: Last electron enters in (n – 1) d orbital.
- This statement is correct. The defining characteristic of transition metals is that their last electron fills the d-orbital, specifically the (n - 1)d subshell.
Statement C: Exhibits variable valency.
- This statement is also correct. Transition metals are known for their ability to exhibit multiple oxidation states due to the involvement of d-electrons in bonding.
Statement D: General electronic configuration is (n – 1) d1–10 ns0–2.
- This statement is true as well. The electronic configuration of transition metals typically involves filling the (n - 1)d subshell, where the d-block can accommodate up to 10 electrons, and ns can have 0 to 2 electrons.
Conclusion
- The incorrect statement among the options provided is **Statement A**, as it misrepresents the range of periods in which transition elements are found. They actually span from the 3rd period through the 6th and beyond.
