Correct answer: D
According to Bohr's Atomic Model, electrons revolve around the nucleus only in certain permitted circular orbits.
Bohr's quantization condition states that the angular momentum of an electron is an integral multiple of h/2π:
where:
m = mass of electron
v = velocity of electron
r = radius of orbit
h = Planck's constant
n = principal quantum number (1, 2, 3, ...)
Thus, angular momentum is quantized and equals an integral multiple of h/2π.
Therefore, the correct answer is Angular Momentum.
