What happens when the compound NaCl is formed?

Sodium transfers an electron to chlorine.

Sodium receives two electrons from chlorine.

Sodium forms an ion with −1 charge and chlorine forms an ion with +1 charge.

Sodium forms an ion with +2 charge and chlorine forms an ion with −2 charge.

Final answer:

When NaCl is formed, sodium atom donates its one electron to chlorine, forming a Na+ cation and a Cl- anion that are held together by ionic bonds.(Option 1)

Step-by-step explanation:

When the compound NaCl is formed, sodium transfers an electron to chlorine. This transfer of electrons results in the formation of ions: the sodium atom loses one electron and becomes a sodium ion (Na+), with a +1 charge, and the chlorine atom gains that electron to become a chloride ion (Cl-), with a -1 charge.

Due to their opposite charges, these ions are strongly attracted to each other, creating an ionic bond. The resulting ionic compound, NaCl, is held together by these ionic bonds in a crystalline lattice structure. Both ions satisfy the octet rule, having complete outermost shells, which is a more stable configuration.
