One Al and three Cl
In most cases,two.
One chlorine atom is needed to bond with one copper II atom to form the compound copper (II) chloride (CuCl2).
Two.
The binary ionic compound formed between zinc and chlorine is zinc chloride (ZnCl2). In this compound, zinc ion has a charge of +2, while each chlorine ion has a charge of -1. Thus, two chlorine ions are needed to balance the charge of one zinc ion.
Four chlorine atoms are needed to form a covalent compound with carbon by sharing electrons. Carbon can form four covalent bonds, so it can share one electron with each of the four chlorine atoms to achieve a stable octet electron configuration.

Compound CIF (Cubic Interpolation Function) contains parameters needed to describe the geometrical arrangement of atoms in a crystal structure. It typically includes atomic coordinates, symmetry operations, lattice parameters, and other relevant information for a specific compound's crystal structure. It is commonly used in crystallography to define and analyze the arrangement of atoms in crystalline materials.
Two atoms of chlorine are needed, one to accept each of the barium electrons in an ionic compound, barium chloride (BaCl2).
The compound formed between barium and chlorine would be barium chloride (BaCl2). In this compound, barium has a +2 charge and chlorine has a -1 charge, so two chlorine atoms are needed to balance the charge of one barium atom.
The formula for an ionic compound containing magnesium and chlorine is MgCl2. Magnesium has a +2 charge, while chlorine has a -1 charge, so two chlorine ions are needed to balance the charge of one magnesium ion.
Chlorine and stabiliser
Rubber is a compound because it is made up of multiple elements, such as carbon and hydrogen, that are chemically bonded together to form the polymer structure of rubber.
