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 Bohr radius in the SI unit is given by-. a 0 = 4 π ε 0 ( h 2 π) 2 m e e 2 = ( h 2 π) m e c α. Where, a o is the Bohr radius. m e is the rest mass of electron. εo is the permittivity of the free space. h/2π = ħ is the reduced Planck constant. c is the velocity of light in a vacuum. α is the fine structure constant.
WebApr 8, 2024 · From this, we can obtain a formula which is used in the calculation of velocity of electrons. m v r = n h 2 π. , n = number of orbit, where m= mass of electron =. 9.1 × 10 − 31 K g. , v = velocity of electron that we need to calculate, r … WebIf you rearrange Bohr's angular momentum equation to solve for the velocity: v = nh/2pmr and then plug that into the equation: mv 2 = kZe 2 /r you get: mn 2 h 2 /4p 2 m 2 r 2 = kZe 2 /r 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. 5.29 x 10-11 m is known as the Bohr radius.
