½. m. 3/2. 4) Write the formula/expression for energy of electron in the n th orbit of hydrogen atom. The Bohr radius (a 0 or r Bohr) is a physical constant, equal to the most probable distance between the nucleus and the electron in a hydrogen atom in its ground state.It is named after Niels Bohr, due to its role in the Bohr model of an atom. Derive an expression for the radius of nth orbit of hydrogen atom using Bohr's postulates. When an atom is in one of these states, it does not radiate any energy but whenever there is a transition from one state to other, energy is emitted or absorbed depending upon the nature of transition. vi. Note that Coulomb’s constant is not required if the unit kg. After the derivation of velocity and radius for the nth orbit, you can calculate its orbital period. Interpret the nature of variation of the radius of orbit with the principal quantum number n. where m is the mass, v is the velocity, r is the radius of the orbit, h is Planck's constant and n is a positive integer. v. The negative sign in equation (v) shows that the electron is bound to the nucleus by an attractive force and hence energy must be supplied to the electron in order to make it free from the influence of the nucleus. The centripetal force between the electron and the nucleus is balanced by the coulombic attraction between them: 2 2. This is required expression for energy of electron in nth orbit of Bohr’s hydrogen atom. School of Chemical Sciences, Universiti Sains Malaysia KTT 111 : Inorganic Chemistry 1 Prepared by V.Manoharan vmano@usm.my manovv1955@yahoo.com 04-6533888 ext 3566 . The gravitational attraction between electron and proton in a hydrogen atom is weaker than the coulomb attraction by a factor of about 10 –40.

Solving this for the radius of the nth orbit gives: r n = [h 2 /4p 2 mkZe 2] n 2. r n = [5.29 x 10-11 m] n 2. asked Jun 11, 2018 in Physics by Nisa (59.4k points) Derive the expression for the radius of the nth orbit of hydrogen atom using Bohr's postulates. Using the definition of ao in equation (5), we can rewrite equation (4) to obtain a more compact form of the radius equation for any one-electron atom: r ' (6) n2a o Z Its value is 5.291 772 109 03 (80) × 10 −11 m. Derivation of Bohr orbit Energy, E and radius, r n for HYDROGEN-LIKE ATOM . For the hydrogen atom (Z = 1), the smallest radius, given the symbol ao, is obtained from equation (4) when n = 1: ao ' (5) h2 4π2me2 '0.529 D This is called the Bohr radius. 6) How do you calculate the total energy of electron in the n th stationary orbit of hydrogen atom?

Since ε o, m, h, π, e are constant ∴ E ∝ 1 / n². Derivation of Bohr orbit Energy, E and radius, r n for HYDROGEN-LIKE ATOM . 5.29 x 10-11 m is known as the Bohr radius. derive the expression for the radius of the nth orbit of hydrogen atom using bohrs postulates show graphically the nature of variation of the radius o - Physics - TopperLearning.com | ldzedtsqq HYDR06a-L/k.E FOR ,97ðm SYSTEM … s-1. Thus the energy of an electron in Bohr’s orbit of an atom is inversely proportional to the square of the principal quantum number. HYDR06a-L/k.E FOR ,97ðm SYSTEM -co ze2 . Derive the expression for the radius of the nth orbit of hydrogen atom using Bohr's postulates. For an electron of hydrogen moving with a constant speed v along a circle of radius R with the center at the nucleus, the force acting on the electron according to Coulomb’s law is: F = e2/4πε0R2 The acceleration of the electron is given by v2/r. School of Chemical Sciences, Universiti Sains Malaysia KTT 111 : Inorganic Chemistry 1 Prepared by V.Manoharan vmano@usm.my manovv1955@yahoo.com 04-6533888 ext 3566 . 7) The energy of an electron in the nth Bohr's orbit … You will find the answer interesting. 2. r Ze r mv =, where Z = atomic number and e = charge of electron . So, Bohr's assumption that the angular momentum is quantized produces the result that the radii of the electron's allowed orbits are also quantized. An alternative way of looking at this fact is to estimate the radius of the first Bohr orbit of a hydrogen atom if the electron and proton were bound by gravitational attraction. RADIUS OF BOHR'S nth ORBIT FORMULA & RATIOS IIT JEE Which hydrogen like species will have same radius as that of Bohr's first orbit of hydrogen atom? This is the required expression for the energy of the electron in Bohr’s orbit of an atom.
