Answer:
If the energy of an electron in Hydrogen atom is given by expression, −1312/n2kJmol−1, then the energy required to excite the electron from ground state to second orbit is.
The formula defining the energy levels of a Hydrogen atom are given by the equation: E = -E0/n2, where E0 = 13.6 eV (1 eV = 1.602×10-19 Joules) and n = 1,2,3… and so on. The energy is expressed as a negative number because it takes that much energy to unbind (ionize) the electron from the nucleus.
