Aluminum is found in lakes as well as the air. Aluminum is element that is in the boron group of chemical elements.
are tin and antimony in the same element group
B (boron) apex
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.
