There are 4 atoms of aluminum in 2Al2O3.
1,46 moles of aluminum fluoride contain 35,16848.10e23 atoms.
Lots of elements can be rolled very to make a foil:gold - used as gold leaf for gilding wood and many other objectssilver - much cheaper than gold and was used to wrap things beforealuminum came along - used to wrap food, chocolate, etc.
6.3x10^24 aluminum atoms represent 1 mole of aluminum atoms because Avogadro's number is approximately 6.022x10^23.

There are 4 atoms of aluminum in 2Al2O3.
Aluminum does not contain any atoms of nitrogen; it only contains one type of atoms, which is aluminum.
The compound is aluminum chloride (AlCl3). In this compound, there are three aluminum atoms and nine chlorine atoms (3 times as many as aluminum atoms).
There are 3 atoms of chlorine in aluminum chloride (AlCl3).
Aluminum oxide has a chemical formula of Al2O3, which means there are 2 aluminum atoms and 3 oxygen atoms in each molecule of aluminum oxide.
One molecule of aluminum bromide contains one aluminum atom and three bromine atoms, totaling four atoms.
The composition of aluminum foil is NOT 100% pure aluminum, as many people believe. You may have noticed that aluminum foil always seems dull on one side, and shiny on the other. This is caused by a naturally-occurring reaction. When Aluminum comes into contact with oxygen, the two elements undergo a spontaneous reaction: 4 Al(S) + 3 O2 (G) => 2 Al2O3 (S) The aluminum foil reacts with oxygen in the air to form a thin layer of Aluminum Oxide on one side of the foil. Because rolls of aluminum foil are generally rolled tightly, the inner side of the aluminum foil is not exposed to the air as much, and it remains shiny. In short, the composition of aluminum foil is pure aluminum (Al) AND aluminum oxide (AL2O3). (And don't worry-- the layer of aluminum oxide on aluminum foil is completely harmless. We've been using foil to cover food for years, after all.)
There are 4 atoms of aluminum in 2Al2O3. Each formula unit of Al2O3 contains 2 atoms of aluminum. Therefore, when we have 2 formula units (2Al2O3), we have a total of 4 aluminum atoms.
The number of aluminium atoms is 0,4284.10e23.
In aluminum chloride (AlCl3), there is 1 aluminum atom (Al) and 3 chlorine atoms (Cl) per molecule.
