SUMMARY
The energy of a K X-ray photon in tantalum, with an atomic number of Z = 73, can be calculated using the formula Energy = -(13.6 eV)Z^2/n^2. For K transitions, the principal quantum number n is 1. Therefore, substituting these values results in an energy of approximately -13.6 eV * (73^2) = -68,000 eV, which converts to joules as needed for further calculations.
