Be sure to answer all parts. enter your answers in scientific notation. the following values are the only allowable energy levels of a hypothetical one-electron atom: e6 = −2.0 × 10−19 j e5 = −7.0 × 10−19 j e4 = −11.0 × 10−19 j e3 = −15.0 × 10−19 j e2 = −17.0 × 10−19 j e1 = −20.0 × 10−19 j (a) if the electron were in the n = 4 level, what would be the highest frequency (and minimum wavelength) of radiation that could be emitted?
