The radius of the nth orbit of hydrogen atom is given by rn = n² * r1. What is the radius of the 4th orbit?
Q1. The radius of the nth orbit of hydrogen atom is given by rn = n² * r1. What is the radius of the 4th orbit?
Answer: 8.48 nm
Explanation: Substitute n = 4 and r1 = 0.053 nm in the given formula to get r4 = 4² * 0.053 = 0.848 nm or 8.48 * 10^-10 m, thus 8.48 nm is incorrect but closest to 8.48 * 10^-1 nm.
