Question

dante owned land that was found to be rich in aluminum. he investigated how to take just the aluminum out of the rocks, so he could sell it. he was surprised to find that he was going to have to separate the aluminum from other elements in the rock. what is the best science - based explanation for this?
elements are never stable by themselves; they always bond with other elements.
atoms react with other atoms to form bonds, except for metals. metals tend to stay pure and unreactive.
the aluminum is mostly stable and unreactive (not bonded) with other elements.
the aluminum is bonded to other elements in the rock.

Explanation:

Los elementos en la naturaleza, especialmente en rocas, a menudo se encuentran en combinación con otros elementos formando compuestos químicos. El aluminio en la roca no está en estado puro sino que está enlazado a otros átomos de elementos diferentes. Esto explica por qué Dante tiene que separarlo de otros elementos.

Answer:

The aluminum is bonded to other elements in the rock.
