Bohr Model Video Lessons

Concept:

# Problem: Determine the energy of an electron in the given quantum level of each of the following ions. (Hint: Each of the ions has a different number of protons, but each has only one electron, so the Bohr model applies.)(a) Li2+ with n = 2(b) O7+ with n = 6

To determine the energy of an electron in the given quantum level of each ion, we use:

$\overline{){{\mathbf{E}}}_{{\mathbf{n}}}{\mathbf{=}}{\mathbf{-}}{{\mathbf{R}}}_{{\mathbf{H}}}{\mathbf{\left(}}\frac{\mathbf{1}}{{\mathbf{n}}^{\mathbf{2}}}{\mathbf{\right)}}}$

En = energy in J

RH = Rydberg constant, 2.178 x 10-18 J

n = principal energy level
