Idon’t know how to do my chemistry homework and it’s chemical reactions how can i be able to do this? _mgcl2 -> _mg+ _cl2

MgCl₂  →  Mg²⁺ + Cl₂

Explanation:

The given equation is incorrect because Mg shows +2 oxidation state.

Correct chemical equation:

MgCl₂  →  Mg²⁺ + Cl₂

Magnesium is present in group two of periodic table.

It is alkaline earth metal.

It has two valance electrons.

Thus by losing two valance electrons it  complete the octet. The common oxidation state of magnesium is +2.

The chlorine is present in group seventeen.

It has seven valance electrons.

It is the member of halogen family.

To complete the octet chlorine required one electron. By gaining the one electron it showed -1 oxidation state.

When chlorine combine with magnesium both formed MgCl₂.

The one atom of Mg have +2 oxidation state while chlorine have -1 that's why to make the overall compound neutral two chlorine atoms combine with one atom of magnesium.

When compound is break, two chlorine atoms combine with each other sharing the electrons and form covalent bond. While Mg atom formed Mg⁺² cation.

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
