How many atoms of aluminum combine to form a molecule?

Aluminum atom is happy by itself, so it remains a single aluminum atom. Atoms in a molecule are held together by covalent or ioinc bonds. A collection of aluminum atoms are not held together by any such covalent or ionic bonds. read more

Aluminum is a metal, so it has a tendency to form large collections of atoms. These collections are not called molecules, because there is no fixed number of them (like there is for O2, NH3 or S8). read more

An atom is a life giving particle, with which you can combine to form various other types of solids, liquids or gases. When atoms or elements combine, they are called molecules. When molecules combine they form compounds. Elements is just another fancy way of saying ‘one single atom’. read more

The relationship between moles of atoms in 1 mole of molecules is given by the subscript of atoms. Thus, 1 mol of glucose molecule would contain 6 mol of C atoms, 12 mol of H atoms, and 6 mol of O atoms. 0.5 mol of glucose would contain half as many moles of each atom, or 3 mol of C atoms, 6 mol of H atoms, and 3 mol of O atoms. read more
