Silver has a density of 10.5 g/cm^(3), mercury has a density of 13.5 g/cm^(3) (both at room temperature). Silver floats initially, but you'll get silver in the mercury and mercury in the silver quickly (here is a video).

Still looks like it would float for a very long time, especially without all the agitation shown in the video.

At 25°C, Silver (Ag) = 10.49g/cm^3 and Mercury (Hg) = 13.53g/cm^3

Given this, at STP (25°C, 1atm) Ag would be solid and Hg would be liquid. Therefore they would not be mixing into a solution. I assume these facts to be evident, but I am stating them just to be safe.

Since Ag has a lower density than Hg, the Ag would float on the Hg.

If you have any follow up questions, I will be glad to answer.
