Questions and Answers

Why does the formation of a triple bond in a nitrogen molecule require both atoms to share six electrons?

To decrease the bond length.

To achieve a stable noble gas electron configuration. (correct)

To achieve a stable octet electron configuration.

To increase the bond strength.

What determines the bond strength of a bond?

The electronegativity of the atoms.

The number of shared electrons. (correct)

The bond length.

The number of participating atoms.

How is a triple bond represented in chemical notation?

With three parallel lines. (correct)

With three dots between the atoms.

With a single line.

With two parallel lines.
