Question

energy of an electron in the second Bohr orbit is -3.4ev calculate the energy of an electron in the third Bohr orbit.​

Answer 1

Answer:

The energy of the electron in the second and third Bohr's orbitals of the hydrogen atom is -5.42×10-12erg and -2.42×10-12erg respectively ,Calculate the wavelength of the emitted radiation when the electron drop from the third to the second orbit.

Answer 2

Answer:

Yo

Energy of electron revolving in nth orbit is;

En = -13.6/n^2 eV

thus energy of electron revolving in (n =3)

E3 = -13.6/3^2 eV

E3. =-13.6/9 eV

E3. = -1.51 eV

this is the required answer dear
