The number of Cl atoms of each compound is based on its subscript index
Further explanation
The naming of chemical compounds is giving a special name to a compound that aims to facilitate the classification of compounds and facilitate the identification of a compound. The rules for naming chemical compounds have been determined by the IUPAC (International Union of Pure and Applied Chemistry)
This nomenclature includes the naming of ion compounds, covalent compounds, and polyatomic
For ionic compounds consisting of cations (ions +) and anions (ions -)
The naming is preceded by the cation then the anion with the -ide suffix added
Generally for this ion compound consists of metal elements as cations and non-metals as anions
- 1. For metal and non-metal compounds
Metal: cation, positively charged.
Nonmetal: negative anion.
The anion cation's charge is crossed
Example:
Fe₂S₃
Fe charge = +3
S charge = -2
The name: metal + non-metal + -ide
Example: BaCl₂ -> Barium chloride
For transition metals, which have several oxidation charges / numbers, write the oxidation number in roman numbers
Example: SnO: lead (II) oxide
SnO₂: lead (IV) oxide
- 2. For metal and non-metal compounds
The naming: name non-metal + non-metal + suffix -ide
In the elements given the prefix mono, di, tri, tetra, penta if more than one element is formed
Example:
SO₂: Sulfur dioxide
SO₃: Sulfur trioxide
The question that needs to be completed is

Cl = 3 atoms
Cl = 5 atoms
Cl = 1 atom
Cl = 2 atoms
Cl = 1 atom
Cl = 2 atoms
Cl = 2 atoms
Cl = 4 atoms
