Textbook Problem

Look up the values of the quantities in a B = h 2 4 π 2 m e k q e 2 , and verify that the Bohr radius a B is 0.529 × 10 10 m.

To determine

To prove:

The Bohr radiusaB is0.529×1010m when the values of the quantities inaB=h24π2mekqe2

Explanation

Given Data:

GivenaB=h24π2mekqe2

Formula Used:

Bohr radius is given as

rB=h24π2mekqe2

WhererB= Bohr's radius

h= Planck's Constant

me= Mass of electron

k= Electrostatic Constant

qe= Charge of electron

Calculation:

We have

  h=6.626×1034J.s

  me=9.11×1031kg

  qe=1.60×1019C

  k=9×109N
