Helium gas is commonly used to fill party balloons because it is lighter than air, making the balloons float.
hydrogen
Tritium is lighter than deuterium. Tritium is a hydrogen isotope with one proton and two neutrons, making it heavier than regular hydrogen but lighter than deuterium, which has one proton and one neutron.
No, aluminum is not heavier when it is corroded. Corrosion is a chemical reaction that occurs on the surface of metals, including aluminum, when exposed to moisture and oxygen. It forms a layer of aluminum oxide, which is actually lighter than aluminum itself.
Rhenium
heavier because they are two different weights
Sevoflurane is considered more toxic than nitrous oxide. Sevoflurane can potentially cause liver and kidney damage if used in high concentrations or for prolonged periods, while nitrous oxide is generally considered safe when used appropriately.
No, Nitrous oxide is not an element. Laughing gas, as it's more commonly known as, is a molecule, which is a combination of more than one element. This molecule consists of, 1 Oxygen and 2 Nitrogen atoms (both of which are elements).
Helium is lighter than air
no
LIGHTER
Gold is heavier than lead, but lighter than tungsten.
Just, simply, Lighter than Air Vehicles are lighter than air, so that makes them fly, and Heavier than air vehicles are heavier than air, but they use airfoils on the wings to fly.

rhenium
One is lighter and the other one is heavier. :D
