PCl3
One zinc atom = Zn Two chlorine atoms = Cl2 Chemical formula for zinc choride compound = ZnCl2
In magnesium chloride, MgCl2, there are two chlorine atoms for every magnesium atom as chlorine is found as a compound.
The ratio of zinc to chlorine in zinc chloride is one to two. For every atom of zinc (Zn), we'll find two chlorine (Cl) atoms bonded to it. It's chemical formula is ZnCl2, just as you'd expect it to be. A link can be found below.
There is 1 hydrogen atom and 1 chlorine atom in Hydrogen Chloride.
Calcium ( Ca ) donates two electrons to this ionic bond and chlorine ( Cl ) accepts one electron to form its octet. So, you need two chlorine atoms for every one of the calcium atoms.

One zinc atom = Zn Two chlorine atoms = Cl2 Chemical formula for zinc choride compound = ZnCl2
The chemical formula of zinc chloride is ZnCl2.
The formula for Zinc Chloride is ZnCl2. That means that for every 1 atom of Zinc there are 2 atoms of chlorine.
In magnesium chloride, MgCl2, there are two chlorine atoms for every magnesium atom as chlorine is found as a compound.
If you know your Classics (Latin), the name gives the clue . 'Tetra' means four(4). So carbon tetrachloride is has four chlorine atoms. Its modern IUPAC name is 'Tetrachlormethane'. It has the formula 'CCl4'.
Fe + 2x Cl = Fe + Cl + Cl = 3 atoms per molecule.
Aluminum Chloride has a formula of AlCl3 giving it 4 total atoms per molecule. Aluminum has a charge of +3 and Chlorine's most common charge is -1 meaning you need 3 chlorine for every 1 Aluminum to cancel the charges.Because of the chlorine, it would most likely be aqueous, or dissolved in a liquid.
The ratio of zinc to chlorine in zinc chloride is one to two. For every atom of zinc (Zn), we'll find two chlorine (Cl) atoms bonded to it. It's chemical formula is ZnCl2, just as you'd expect it to be. A link can be found below.
In sulphur hexachloride SCl6 there are two elements, sulphur and chlorine, with six atoms of chlorine for every one of sulphur.
There is 1 hydrogen atom and 1 chlorine atom in Hydrogen Chloride.
