Thus the radius of the Bohr’s orbit of an atom is directly proportional to the square of the principal quantum number. The Expression for Velocity of Electron in …
WebApr 15, 2024 · If 'e,' 'm,' and 'v' be the charge, mass, and velocity of the electron respectively, 'r' be the radius of the orbit, and Z be the atomic number, the equation for the radii of the permitted orbits is given by r = n 2 xr 1, where 'n' is the principal quantum number, and r 1 is the least allowed radius for a hydrogen atom, known as Bohr's radius ... 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 = n2h2 / 4π2kmq1q2 we can replace this in the above equation to give us:-

WebWe will apply the expression (1) in the case of the proton and electron of the hydrogen atom. The proton has a positive charge equal in magnitude to a unit of electron charge e (= 1.60 × 10 -19 C). In the ground state of hydrogen atom, its Bohr radius a0 = 5.3 × 10-11 m.
