An aluminum nail that is less dense than the element aluminum would not be made of pure aluminum, but would have to be an alloy of aluminum and some other substance. If an aluminum nail is made of pure aluminum, it would have the same density as the "actual" element.
Aluminum.
yep
Aluminium is more dense than PET.
Aluminum is less electronegative than silicon.
No, gold is much more dense that aluminum.
maybe proton
The nucleus of an aluminum atom weights half that of an iron atom. Not only that, but the spacing between aluminum atoms is greater (its fluffier) so the two effects make aluminum less dense.
Oxygen is less dense than selenium. Oxygen has a density of about 1.43 grams per cubic centimeter, while selenium has a density of about 4.81 grams per cubic centimeter.
Hydrogen gas is considered the least dense element. It is less dense than air, which is why it is often used in balloons.
Because it contains a lot of hydrogen. Aluminum is considerably less dense than lead, but a cubic meter of aluminum weighs a lot more than a cubic centimeter of lead because it's so much bigger.
The percentage of aluminum in an igneous rock generally affects its density because aluminum is a lighter element compared to heavier elements like iron and magnesium. Higher aluminum content typically results in lower overall density, as rocks rich in aluminum tend to have a more felsic composition, which is less dense than mafic compositions that are higher in iron and magnesium. Thus, as the aluminum content increases, the density of the rock tends to decrease.
Yes, aluminum can float in corn syrup. The buoyancy of an object in a liquid depends on its density relative to the liquid. Since aluminum is less dense than corn syrup, it will remain on the surface rather than sinking. However, if the aluminum is in the form of a dense enough object, such as a solid piece, it may sink in some scenarios.
