Velocity of Electron in Bohr

WebBig Chemical Encyclopedia Bohr velocity There is a widespread opinion that stopping of projectiles at velocities below the Bohr velocity is essentially quantal. The claim appears plausible for insulators to the extent that electron promotion may be an essential sink of energy. [Pg.107] WebE 1 = -13.6 eV. Hence, the minimum energy required to free an electron from the ground state of an atom is 13.6 eV. This energy is the ‘Ionization Energy’ of the hydrogen atom. This value agrees with the experimental value of ionization energy too. Now, a hydrogen atom is usually in ‘Ground State’ at room temperature. WebThe angular momentum of an electron by Bohr is given by mvr or nh/2π (where v is the velocity, n is the orbit in which the electron is revolving, m is mass of the electron, and r is the radius of the nth orbit).
