Question

What is the energy of an electron found in the fifth quantum energy level of an iron atom?

Options:

27 eV

14 eV

1840 eV

368 eV

Please hurry and thank you in advance!

Answer 1

Answer #1

368 eV.

E_n is proportional to z²

Here z= 26 and n= 5

E₅ = -13.6 × z² / n²

^{= -368 eV}

Answer 2
