Why do magnesium and chlorine bond the way they do

Answers

GPT 3.5
Magnesium and chlorine bond in a specific way due to the transfer of electrons between the two elements. Magnesium has two valence electrons in its outermost energy level, while chlorine has seven valence electrons. Both elements seek stability by achieving a full outermost energy level, which can be achieved by either gaining or losing electrons.

Magnesium tends to lose its two valence electrons to achieve a stable configuration like that of a noble gas (neon), resulting in a +2 ionic charge. This loss of electrons allows magnesium to have a complete octet structure in its lower energy levels.

Chlorine, on the other hand, seeks to gain one electron to complete its octet structure, resulting in a -1 ionic charge. By accepting the two electrons lost by magnesium, chlorine achieves a stable configuration like that of a noble gas (argon).

Due to the opposite charges of magnesium and chlorine ions, they are attracted to each other, resulting in the formation of an ionic bond. The magnesium cation (Mg2+) is attracted to the chlorine anion (Cl-), creating an electrostatic bond between the two ions. This bond holds the resulting compound, magnesium chloride (MgCl2), together.

In summary, magnesium and chlorine bond in a way that allows both elements to achieve a stable electron configuration and a full outermost energy level, resulting in the formation of an ionic bond between the magnesium cation and chlorine anion.
