I'll solve this problem step by step, carefully following the LaTeX formatting guidelines:

Step 2
: Analyze the Lewis Structure

The given Lewis structure shows acetylene ($$\mathrm{C}_{2}\mathrm{H}_{2}$$) with a triple bond between the carbon atoms and single bonds to the hydrogen atoms.

Final Answer

- Bonding pairs: 1 - Lone pairs: 0 Key Insight: In the Lewis structure of acetylene, each hydrogen atom forms a single bond with a carbon atom and has no lone pairs of electrons.
