Which of the following is true of ionic bonds? Moving electrons become delocalized between the atoms creating the
ionic bond
Electrostatic attraction results in the arrangement of charged atoms in a
regular, geometric structure called a crystal lattice.
Transferring of valence electrons creates the bond
The bond is created by oppositely charged metal and nonmetal atoms
Sharing Valence electrons between nonmetal atoms creates the bond

D: The bond is created by oppositely charged metal and nonmetal atoms.

Explanation:

An ionic metal basically involves a metal and a nonmetal in bonding. A metal is a cation with a + charge and a nonmetal is a anion with a - charge. I will give you an example. Magnesium Chloride is a ionic bond. This is because Magnesium is a metal with a +2 charge(so it is a cation). Chloride or Chlorine is a nonmetal because it has a -1 charge.(so it is a anion). The chemical formula for magnesium chloride is MgCl2.

Hope my answer helped! Have a great day.

it means there are 3 atoms of oxygen

the correct answer would be d. hope this !
