The reaction is already balanced as it is written: Cl₂ + 2Kl → 2KCl + Cl₂. Each side of the reaction has the same number of atoms for each element.
The balanced reaction is: 2Cl + 2KI → 2KCl + I2. It is balanced by ensuring there are the same number of each type of atom on both sides of the reaction arrow.
Sodium - it goes from oxidation number 0 to +1
To find the nuclear charge of chlorine with 22 neutrons, you need to know the atomic number of chlorine, which is 17. The nuclear charge is equal to the atomic number plus the number of neutrons, so in this case, it would be 17 (atomic number) + 22 (neutrons) = 39.

To find the missing number, we first perform the calculation: 83 - 17 equals 66. Then, we need to determine what number plus 56 equals 66. The missing number is 10, because 10 + 56 = 66.
