Bohr model

6. Using the Bohr model, determine the energy of an electron with n = 8 in a hydrogen atom. 

[ΔE= 2.179 x10-18(Z)2((1/n12)-(1/n22))]

- 3.405 x 10-20J

- 1.703 x 10-20J

+ 1.703 x 10-20J

+ 3.405 x 10-20J

 

7.Using the Bohr model, determine the energy in joules of the photon produced when an electron in a Li2+ ion moves from the orbit with n = 2 to the orbit with n = 1. 

[ΔE= 2.179 x10-18(Z)2((1/n12)-(1/n22))]

-9.81 x 10-18J

-1.63 x 10-18J

-4.90 x 10-18J

-1.471 x 10-17J
