AI2O3 is the chemical formula for sapphire crystals: http://www.redoptronics.com/Sapphire-crystal.html
It is a compound.
There is no such substance as ai2o3 in chemistry. However, Al2O3 (with a lowercase L, not an i) is an ionic compound.
SiO2 as it exists in linear and branched chains

Aluminium oxide is a compound.
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.)
SiO2 as it exists in linear and branched chains
There are 20 atoms and there are 6 Carbon atoms, 8 Hydrogen atoms, 6 Oxygen atoms.

A molecule is a combination of atoms. To know how many atoms are in one molecule, you have to find out what atoms are in the molecule.
there are fifteen atoms
