In fact there are seven elements lighter than oxygen: hydrogen, helium, lithium, beryllium, boron, carbon and nitrogen.
Nitrogen is lighter than oxygen
carbon dioxide is heavier than oxygen therefore oxygen is lighter.
nitrogen is lighter than oxygen
A neutrino is lighter than the photon
In what? Oxygen is much lighter than water.
no. If it was, we would have oxygen balloons instead of helium balloons.
yes, anything with a lower atomic number would be lighter, for example, helium is lighter than air, which is why balloons float when filled with helium... the lighter substance rises above the heavier....
dakota
yes at ATM and temp
Water vapor is a gas so it is in the air. Nitrogen and nitrogen are in the air too, but there is more nitrogen than anything in the air. I believe it rises because it is lighter, like a balloon filled with helium.
A compound is not lighter than an element, if that element is part of the compound. Some compounds, like H2O would be lighter than, say, the element lead, but it is not lighter than the elements that make it up, i.e. hydgrogen and/or oxygen.
Helium is lighter (less dense) than oxygen & nitrogen.
