Just about anything that is lighter then Mercury. Dont be tempted to put your gold ring on mercury as it will dissolve in it, and let of a toxic gas while doing so Iron, water, sand, lead, wood, All the things that are lighter then Mercury.
Anything that is less dense than mercury (13.55 g/mL) can float.
This only applies to solids though.
Anything that is denser (mass/volume) (ignoring shape). (A ship floats in water, but steel does not; yet a ship is made from steel -- shape.)

Oil is denser than cork, so the cork would float.
No.
Depends on the medium, and whether the ball is solid or not. A solid ball would float on mercury, sink in water. If it were hollow enough (or filled with, say, cork) it would float in water.
A hydrometer consists of a cylindrical stem and a bulb weighted with mercury or lead shot to make it float upright. Mercury has a higher density, thus a lower volume for the same weight than lead. It is a toxic liquid metal, but also more dangerous and difficult to clear up the mess when a glass hydrometer is broken
There are tents designed to Float in water. But not all tents designed to float.
it will float
Strictly be density, nickel should float on mercury.
Solid iron will float in liquid mercury. In most liquids it will sink.
No, they are not bouyant. They won't float on water, but they will float on mercury.
Oil is denser than cork, so the cork would float.
yes it will
No, it sinks.
No.
steel will float in mercury
Lead floats in mercury.
Most materials will float in Mercury because it is so dense. A lump of Lead will float in a bath of Mercury. The well-known metals Gold, Platinum, Tungsten, Uranium and Plutonium are more dense than mercury and would sink. More specifically, any material having a density less than 13593 Kg/m3 will float in a bath of Mercury.
Mercury would not float on water. This is because the density of Mercury (5427kg/m3) is greater than the density of water (1000kg/m3).
