The radius of Bohr's atom depends on the following?

Explanation

According to Bohr's model of the atom, electrons occupy certain energy levels or orbits around the nucleus. These energy levels are represented by the quantum number "n," where n = 1, 2, 3, and so on. The radius of the Bohr atom, which represents the average distance between the electron and the nucleus, is related to the quantum number "n."Bohr's model states that the radius of the electron orbit is directly proportional to the square of the quantum number. Therefore, the radius of the Bohr atom is given by the expressionr =(4πε0n²)/(me²)where "(4πε0)/(me²)" is a constant factor.This means that as the value of "n" increases, the radius of the orbit increases exponentially. The square of the quantum number, n2, plays a significant role in determining the size of the Bohr atom. Thus, the correct answer is B) n2.
