The energy levels the electron can occupy in the Be3+ ion can be calculated using the energy level equation. A Be3+ ion with an electron in the n= 3.00 level emitted a photon with a frequency of 7.30 × 1015 Hz. What is the value of the level n for the new energy?

  1. E = h*frequency = ?
    E =? = 2.18E-19 x Z^2 (1/x^2 - 1/3^2)
    Z is 4 for Be^3+
    Solve for x, the new energy level. I believe the answer is 2.
