Bohrs velocity

WebApr 8, 2024 · Hence the velocity of the electron in the first Bohr orbit of the hydrogen atom is \[2.18 \times {10^6}m/\sec \]. Note: Mass used in the above formula is not the molecular weight of hydrogen, it is the mass of protons of hydrogen atom. And r is the radius of the orbit. So, don't confuse among them. WebFor the first orbit of the hydrogen atom, n = 1 and Z = 1, we have r = 52.9 pm which is called the Bohr Radius. Deriving Velocity of an Electron in a Stationary State. From the Bohr’s Quantization Principle we have :-L = n(h/2π) ⇒ mvr = n(h/2π) ⇒ v = n(h/2πmr) Since r = n 2 h 2 / 4π 2 kmq 1 q 2 we can replace this in the above ...
