  1. Question 1

    Q1. The radius of the nth orbit is given by rn = n² * r1, where r1 = 0.53 Å. What is the radius of the 2nd orbit?

    • A) 2.12 Å
    • B) 1.06 Å
    • C) 0.53 Å
    • D) 4.24 Å

    Answer: 2.12 Å

    Explanation: Substitute n = 2 in rn = n² * r1 to get r2 = 2² * 0.53 Å = 2.12 Å.
