Question

which type of bond has one pair of electrons shared between atoms?
○ coordinate covalent
○ single covalent
○ double covalent
○ metallic

Explanation:

To determine the bond with one pair of shared electrons:

• Coordinate covalent: Electrons from one atom, not one pair shared equally in a typical sense.
• Single covalent: Involves sharing one pair (2 electrons) between atoms.
• Double covalent: Shares two pairs (4 electrons).
• Metallic: Involves delocalized electrons, not shared pairs between two atoms.

So the single covalent bond matches.

Answer:

B. single covalent
