Question

Calculat the ionization energy of hydrogen atom using bohrs theory

Answer 1

ionization energy is the energy Required to ionise electron( Remove electron ) from outer most orbit of isolated gaseous atom .

For Hydrogen Atom Outer Most Orbir is 1st orbit or ground state .

So , Enegry Required to Remove Electron From nth orbit of hydrogen atom = 13.6 / n² ev....

So , Enegry Required to Remove Electron From 1st orbit of hydrogen atom = 13.6 ev.

ionization energy of hydrogen atom = 13.6 ev .( Answer ) .

ev is the electron volt

1 ev is 1.6 *10^-19 j .

So, ionization energy of hydrogen atom = 13.6 * 1.6 * 10^-19j = 2.176 * 10^-18 j. ( Answer ) .
