Answer
It takes much more energy to remove a 1s electron from gold than to remove a 1s electron from hydrogen.
Work Step by Step
When a core electron is removed from a heavy atom, this is known as an Auger process.
The gold 1s electron is more strongly attracted to the more positive nucleus, though the effective Z (page 1390) is much less than 79 due to electron screening.
For a hydrogen atom, an ultraviolet photon can ionize it, but for gold, an x-ray photon is required.
