(adsbygoogle = window.adsbygoogle || []).push({}); Determine the energy of an electron in the given level of each of the following ions. Use 'e' notation with two decimal places. For example, -2.34e-22.

Hint: Each of the ions has a different number of protons, but each has one electron, so the Bohr model applies to each.

Ions:

Li2+

F8+

Level:

Li^(2+) = 2

F^(8+) = 6

Find Enegery of

Li^(2+) and F^(8+);

Our professor doesn't know how to get it for some reason, he said he might just take it off the hw, but it doesn't seem that hard but maybe we are using hte wrong formula.

In his notes this is the only thing close to what i think it would be:

Oscillating molecules that emit the radiation only have discrete energies

E_n = nhf

f = frequencey

h = planks constant;

n = quantum number

E_n = energy of quantum state n of molecule

for Li^(2+), i'm trying:

Li (Z = 3)

E_n = (3)(6.62E-35Js)(f)

problem is, we don't know the frequency!

any ideas on what other formulas i could use? thanks!

He told us, take Z multiply it by planks constant for ur answer, when we told him it didn't work he said it should have worked hah. SO i dunno whats going on!
