For nitric acid (\( \text{HNO}_3 \)), calculate the difference between the total number of valence electrons and the number of electrons involved in forming covalent bonds as represented in its complete octet Lewis structure.

  1. \( 14 \)
  2. \( 16 \)
  3. \( 10 \)
  4. \( 12 \)

Correct answer · Option 1

\( 14 \)

Explanation

Total valence electrons = \( 1 + 5 + 3(6) = 24 \). Number of bonding electrons = 10 (5 bonds). The difference (lone pair electrons) is \( 24 - 10 = 14 \).
