(Density) = (Molar Mass) * (Pressure) / (Temperature) * (R Constant)
or (D=P*n/T*R)
This shows it depends on the temperature of the helium. If the helium is in a state where the density is less than water then it floats if its density is greater than water then no it will not float.
No it does not. Being in group 18 (the halogen group), helium is a very stable and inert element. Its electronic configuration is 1s2 which means it has the stable duplet structure, one of the noble gas configurations. Thus it has neither a tendency to gain or lose electrons, nor is there any necessity to share them with others, which is why helium exists as a monatomic element in the atmosphere.
No, helium is a noble gas and does not react with anything.
Helium does not react with water. It does, however, dissolve slightly to the extent of about 8.61 cm3 kg-1 at 20°C (293 K).
Helium does not react with water.
Helium is light and it will float / rise.
The helium weighs less than air- so when the balloon is filled, it displaces the heavier air, and floats. Just as a bit of wood weighs less than water, and floats on water. In a vacuum, a helium filled balloon would not float (but it may pop)
A helium balloon floats because helium gas is lighter than air. By filling a balloon with helium, the balloon also becomes lighter than air. The helium balloon floats for the same reason that objects float on water: objects less dense than water are pushed up by buoyant forces equal to the weight of water displaced by that object. What happens in water also happens in air, and the helium balloon is pushed upwards by a force equal to the weight of air it displaces.
no
Helium is lighter than air. So it will float in air.
fill it with helium
Helium is light and it will float / rise.
Hydrogen and helium are gases and doesn't float on water. Lithium have a very low density but react with water.
NO! be careful because in collage, my professor told my whole class that gases can float on top pf water.
Helium is lighter than air. Hence balloons or blimps filled with helium will float.
Helium is lighter than air. so balloons filled with helium will float in air

No, human body doesn't float on helium as it is light.

Helium
Density water having a density of 1.00 anything .99 or below will float and anything above will sink same scenario for oxygen and gasses for example helium has a lighter density than oxygen and that's why helium filled balloons float
Helium is lighter than air. so balloons filled with helium will float in air. warming will make them float or rise up faster.
