I am pretty sure I just heard this on the BBC 2 program "The Atom"
on now.
Of course this is wrong, they differ by at least one proton, as well as
one
electron, and maybe the odd neutron thrown in.
According to my handy reference book, the most common Isotope of Gold is
Au197 (all others being radioactive). However Mercury exists in stable form
as a mixture of Isotopes, the most common being Hg202 making about 30% of
natural Mercury. This would have 1 electron, 1 proton and 4 neutrons more
than the gold. But Hg200 isn't that far behind in the percentage stakes
forming about 23% of naturally occuring mercury (1 electron, 1 proton and 2
neutrons extra). Hg198 forms 10% of naturally occuring mercury having just
the extra electron and proton. There is a small amount of Hg196 naturally
occuring which has 1 extra electron and proton but 2 *fewer* neutrons.
So you are on the right track.
