Arjun opens Chapter 1: Periodic Properties. Question 1.1: "Arrange the following in order of increasing ionic radius: Na+, Mg2+, Al3+, O2-, F-."
There is a famous, probably apocryphal, story told in Kota: A student once emailed Dr. Jaiswal, "Sir, I have solved your book cover to cover 5 times. But Problem 4.32 still haunts me. What do I do?" v k jaiswal inorganic chemistry
He solves it. Correct.
For every IIT-JEE aspirant, the journey of inorganic chemistry is not measured in months or marks. It is measured in the number of times you have solved V. K. Jaiswal . Arjun opens Chapter 1: Periodic Properties
One post read: "Dear Dr. Jaiswal, you never met me. But you sat with me every night for two years. You taught me that inorganic chemistry is not memorization. It is logic, symmetry, and elegance. You taught me how to fight a problem until it surrenders. Thank you for the green book. Rest in peace, sir." But Problem 4
Question 1.2: "Why is the second ionization energy of sodium greater than the second ionization energy of magnesium?"
