## hejå Group Title An electron in Li2+ falls from n = 2 to the ground state. Calculate the wavenumber, (νˉ), of the emitted photon. one year ago one year ago

U knw Rydbergs Formula....Use it: $\frac{ 1 }{ \lambda } = 109677z^2(\frac{ 1 }{ n1^2 }-\frac{ 1 }{ n2^2) }$ $(νˉ) = \frac{ 1 }{ \lambda }$

2. Yahoo!

n1 = 1 n2 = 2 z = 3

Hope U can Solve the Rest..)
