Homework Statement
In the equation for the bohr model of the atom, what is the n value for Li2+ ion?
Homework Equations
E = -2.178 x 10^-18J(z^2/n^2)
The Attempt at a Solution
Since it is Li2+ that means it has 1 electron. So z = 1. Now I have an equation with 2 variables (impossible to solve).
I don't know what E is and I have to find n. Does anyone have any idea on how to do this?
