If the energy for the ground state level (n = 1)of hydrogen is -13.6 eV,which of the following gives an approximate value for the energy of an electron of the K shell (n = 1)of the element oxygen for which the atomic number = 8?

Question

The energy of an electron in the K shell (n=1) for an element is given by the formula E = -13.6 * Z^2 eV, where Z is the atomic number. For oxygen, Z = 8, so E = -13.6 * 8^2 = -870.4 eV. The closest approximate value given is -666 eV.
