• ionic bond

• crystal

What type of bond forms when metal ions bonding to ligands with 2 electrons?

• covalent bond

• Ionic bond

• coordinate covalent bond

(a)   is a kind of 2-center, 2-electron covalent bond in which the two electrons derive from the same atom.

The difference between covalent and coordinate bond is only one atom is involved in the formation of the (a)   bond.
