Helium is lighter than air. So it will float in air.
Helium is light and it will float / rise.
because helium is ligter than air
No, rocks are denser than mercury, so they would sink in mercury. Mercury is a very dense liquid at room temperature, so objects that are less dense than mercury will float on it.
Helium rises because it is less dense than the surrounding air. On the other hand, carbon dioxide sinks because it is more dense than the surrounding air. This difference in density causes helium to float upward and carbon dioxide to sink downward.
Helium will contract in cold weather, but that may not cause a balloon filled with it to sink since the air will also contract - and by about the same amount - so the relative densities of the helium and the surrounding are would remain about the same and the buoyancy of a helium filled balloon would remain

hydrogen floats at room temperature because it has a density less than 1.
Chlorine is a gas at room temperature and atmospheric pressure, so it cannot sink or float. It is typically stored and transported in tanks as a compressed gas.
Helium gas is less dense than air, so it will rise and float in both air and water.

yes. think about balloons: a ballon with helium will float while a balloon with good ol' air will sink

The the object you speak of is in water at approximately room temperature, then anything with a density above about 1 will sink; anything below 1 will float and anything at very close will be suspended in the water. So, to answer your question, high density equals sinking.
For something to be able to float on water, it requires a density lower than water. Water at room temperature has a density of 1 kg / L or 1000 g / dm3Atomic number 43 is the element Technetium. At room temperature Tc has a density of 11 g / dm3.So yes, it will float on water.
Because Helium is less dense than air, and CO2, I assume is more dense
Nope Most string should float on top of water becomes the string material is less dense than he water.
it will float as long as it is not fully covered water.
