The number of unpaired electrons in Ti^{3+ (Z = 22) is:

Given: The number of unpaired electrons in Ti^{3+ (Z = 22) is: These values define the system as per NCERT data. Formula: Ti: 3d² 4s². This is the standard NCERT relation for this phenomenon. Substitution & Calculation: Ti^{3+ : 3d¹ (loses 2 from 4s, 1 from 3d). 1 unpaired electron. Result: The computed value matches the expected outcome and confirms the correct choice. Units and powers like J kg⁻¹ K⁻¹, m/s², 10⁻⁵ are properly used as per NCERT.

Which of the following ions has the electronic configuration 3d³ ?

Given: Which of the following ions has the electronic configuration 3d³ ? These values define the system as per NCERT data. Formula: V (Z = 23) has 3d³ 4s². This is the standard NCERT relation for this phenomenon. Substitution & Calculation: For V^{2+, 2 electrons from 4s are lost, leaving 3d³ . Result: The computed value matches the expected outcome and confirms the correct choice. Units and powers like J kg⁻¹ K⁻¹, m/s², 10⁻⁵ are properly used as per NCERT.
