The energy of the nth level in a one-electron atom is E_n = -13.6(Z²/n²)eV.Consider a beryllium ion with all but one of its electrons removed (a beryllium atom normally has four electrons).What is the energy of the electron when it is in the third-lowest energy state? A)-24 eV B)-7.6 eV C)-1.5 eV D)24 eV E)7.6 eV
