Question

A A Cl atom donates two electrons to a Mg atomA Cl atom donates two electrons to a Mg atom
B An Mg atom donates two electrons to a Cl atom.An Mg atom donates two electrons to a Cl atom.
C A Cl atom donates one electron to each of the two Mg atoms.A Cl atom donates one electron to each of the two Mg atoms.
D An Mg atom donates one electron to each of the two Cl atoms.

Answer 1

The correct statement is:

D An Mg atom donates one electron to each of the two Cl atoms.

Explanation: Magnesium (Mg) has two electrons in its outer shell and tends to lose both to achieve a stable electronic configuration. Chlorine (Cl) has seven electrons in its outer shell and needs one more electron to achieve stability. Therefore, one Mg atom donates its two electrons, with each Cl atom receiving one electron, resulting in the formation of magnesium chloride (MgCl₂).
