The institute has not announced the fees for the AY 2025-26. When PGIMER will announce the fee, students will be able to pay it using debit or credit card. Last year, the application fee for this course was INR 1,500 for the general and OBC categories and INR 1,200 for the SC/ST category.

PGIMER does not accept the NEET UG score. You need to appear in the PGIMER BSc Nursing exam separately for the BSc Nursing program. To appear in this examination, students must have completed the Class 12 examination with Physics, Chemistry, Biology, and English subjects. A separate counseling will be conducted by PGIMER for granting admission to candidates on the basis of the merit scored in the entrance exam.

To appear in this exam, the students must have completed the BSc Nursing/Post Basic Nursing with a minimum of 55%. It should be completed from a recognised institute. They should also have a minimum of one year of work experience working in a hospital with a minimum of 100 beds. The student should be a registered nurse and registered midwife.

(a) [Cr (H₂O)₆]⁺³ → Cr⁺³ → $t_{2g}^{3}eg°$  

(b) [Fe (H₂O)₆]⁺³ → Fe³⁺ → $t_{2g}^{3}e{g}^2$  

(c) [Ni (H₂O)₆]⁺² → Ni²⁺ → $t_{2g}^{6}e{g}^2$  

(d) [V (H₂O)₆]⁺³ → V³⁺ → $t_{2g}^{2}eg°$  

Polarisation power µ $\frac{Charge}{Size}$ for K⁺, polarising power is least and ionic character is maximum.

Reducing character increases from NH₃ to BiH₃.

Group 15 oxides of type E₂O₃ and E₂O₅ are not always basic.

Ni²⁺ : 4s⁰3d⁸ (No pairing with Cl^–)
