Magnesium must bond with two atoms of chlorine to form magnesium chloride because

• magnesium can share two electrons when bonding and chlorine can share one.

• magnesium can share one electron when bonding and each chlorine can share two.

• magnesium has one valence electron to use in bonding and each chlorine can receive two.

• magnesium has two valence electrons to use in bonding and each chlorine can only receive one.
