Foods grade aluminium is 99,99 % pure.
The chemical formula of aluminium chloride is AlCl3; the ratio Al/Cl is 1/3.
Elements that contain only one type of atom are called pure elements or monatomic elements. For example, helium (He), neon (Ne), and oxygen (O) are pure elements because they consist of only one type of atom in their chemical structure.
The valency of AlCl3 is 3. This is because aluminium (Al) has a valency of +3 and each chlorine atom (Cl) has a valency of -1, so it takes 3 chlorine atoms to balance the charge of one aluminium atom.
no oxygen is an element of one atom and that's an oxygen atom
Aluminium is a metal with a +3 charge, and chlorine is a non-metal with a -1 charge. To balance the charges in a compound, three chlorine atoms are needed for every one aluminium atom. This results in the chemical formula AlCl3 for aluminium chloride.
atom
Elements only contain one kind of atom.
Aluminium chloride (AlCl3) has one aluminium atom (Al) and three chlorine atoms (Cl). The chemical formula AlCl3 indicates that there is one aluminium atom bonded to three chlorine atoms in the compound.
The chemical formula of aluminium chloride is AlCl3; the ratio Al/Cl is 1/3.
