Question

These questions contains, Statement-I (assertion) and Statement-II (reason).

Statement-I : General formula of transition element is (n – 1)d ^1–10 ns^1–2 .

Statement-II : Transition element have 10 electrons in (n–1)d orbitals.

TestHub · Accepted Answer

* Statement-I: True. Transition elements are defined as elements with partially filled $(n - 1) d$ orbitals, so their general configuration is $(n - 1) d^{1 - 10} n s^{1 - 2}$ .

* Statement-II: False. Transition elements do not necessarily have 10 electrons in $(n - 1) d$ orbitals; they have $1 - 10$ electrons depending on the element.

* Therefore, Statement-I is correct, and Statement-II is incorrect.
