There are 13 protons in aluminum and 13 electrons. So, there are 13 atoms in aluminum. In oxygen, there are 8 protons and 8 electrons. thus there are 8 atoms.
EDIT: This answer is absolutely and completely incorrect. (Dr.J.)
In order to answer how many atoms are in aluminum and oxygen, one needs to know the mass of aluminum and oxygen present. The greater the mass, the greater the number of atoms. Each mole will contain 6.02x10^23 atoms.
Aluminum Oxide has two atoms of alminum for every three atoms of oxygen.
EXAMPLE:
AI2O3
Theoritically, according to charge, two atoms are needed. Although as aluminium oxide is an ionic compound, it forms a crystalline lattice.
The chemical formula of aluminium oxide is Al2O3: 2 atoms of aluminium and 3 atoms of oxygen.
Aluminium dioxide doesn't exist.
Al2O3 has 2 aluminium atoms and 3 oxygen atoms.
The general oxide of aluminum is Al2O3
2 Al and 3 O

When aluminum and bromine react, three bromine atoms combine with each aluminum atom.
Oxygen is an element. The oxygen in our atmosphere typically combines with itself, as does the nitrogen, forming a diatomic molecule--O2. So the two atoms in a molecule of oxygen would both be oxygen atoms.
The formula for aluminum chromate is Al2(CrO4)3, so there are 12 oxygen atoms. Multiply the number of oxygen atoms inside the parentheses times the subscript outside the parentheses.
There are 12 oxygen atoms in a molecule of aluminum sulfate. The formula for aluminum sulfate is Al2(SO4)3. This tells us there are 3 sulfate ions, each with 4 oxygen atoms per sulfate, so 3 * 4 = 12.== ==
Sixteen. The formula for aluminum permanganate is Al(MnO4)3. There is one atom of aluminum (Al), three atoms of manganese (Mn), and twelve atoms of oxygen (O).
Aluminum is an element. It is made entirely of aluminum atoms.
Two hydrogen atoms and one oxygen atom combine to form one water molecule.
"Oxygen and sulphur have similar chemical reactions. Sulphur burns in oxygen with a blue flame. It forms the oxide of sulpher called sulpher dioxide. The letters 'di' mean two, so dioxides contain two oxygen atoms." When elements combine with oxygen, you simply add 'dioxide' to the name.
2 aluminum atoms 4 sulphur atoms 4 oxygen atoms
When aluminum and bromine react, three bromine atoms combine with each aluminum atom.
Oxidation
3 Fluorine atoms are required for 1 aluminum atom.
If you mean compounds instead of combines, the answer is yes.
Two aluminum atoms and three oxygen atoms >
The two atoms that combine are a metal atom and an oxygen atom.
Atoms combine to form molecules and atoms are made of subatomic particles (protons, neutrons & electrons).
Oxygen is an element. The oxygen in our atmosphere typically combines with itself, as does the nitrogen, forming a diatomic molecule--O2. So the two atoms in a molecule of oxygen would both be oxygen atoms.
