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.
