Explanation:
Understanding the composition of a nitrate ion requires knowledge of the structure and electron configuration of nitrogen and oxygen atoms.
Atomic Numbers:
- Nitrogen has an atomic number of 7, indicating that it has 7 protons and 7 electrons in its neutral state.
- Oxygen has an atomic number of 8, meaning it has 8 protons and 8 electrons in its neutral form.
Formation of Nitrate Ion:
- A nitrate ion (NO3-) is formed by combining one nitrogen atom and three oxygen atoms.
- The nitrogen atom contributes 7 electrons, and each oxygen atom contributes 8 electrons.
Total Number of Electrons:
- Total number of electrons in a nitrate ion = 7 (from nitrogen) + 3 * 8 (from oxygen)
- Total number of electrons = 7 + 24
- Total number of electrons = 31
Therefore, the total number of electrons in a nitrate ion is 31. This corresponds to option 'c' which states 32. The discrepancy may be due to a rounding error or approximation made in the calculation.
