Apr 15, 2019 · Ordinary mercury contains seven isotopes Hg-196, Hg-198, Hg-199, Hg-200, Hg-201, Hg-202 and Hg-204. When it absorbs a neutron, Hg-196 becomes Hg-197. Hg-197 decays into gold. As a by-product, Hg-202 and Hg-204 become Hg-203 and Hg-205, which decay into thallium. Other isotopes change into each other and remain mercury.
