yes. e.g. Al2O3
Aluminum, like all other elements, comes in a variety of isotopes, and that is normal.

No, aluminum is an element. It has a number of isotopes, however.
its 40,19 K and 39,20 K
Aluminium has 13 protons in all isotopes.
No, density can vary slightly between different samples of aluminum due to factors like impurities or differences in processing. Generally, the density of aluminum is around 2.7 g/cm3, but small variations are possible.
Aluminum and oxygen form aluminum oxide. Aluminum and iodine form aluminum iodide.
Nearly 100% of aluminum found in nature is 27Al, which is not radioactive. There are traces found of radioactive 26Al, but they are not significant. Other, synthetic, radioactive isotopes of aluminum exist, such as 25Al.
The number of neutrons in an aluminum ion can vary depending on the isotope. The most common isotope of aluminum is 27Al, which has 14 neutrons. However, other isotopes of aluminum exist with different numbers of neutrons.
No, aluminum and oxygen are unlikely to form a covalent bond. They are more likely to form an ionic bond, where aluminum loses electrons to oxygen to form aluminum oxide.
