The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n

The correct answer is: Pb\u2083N\u2084<\/strong><\/p>\n\n\n\n

\n\n\n\n

Explanation:<\/h3>\n\n\n\n

To determine the correct chemical formula for plumbic nitride, we need to consider the charges and the correct ratio in which the ions combine to form a neutral compound.<\/p>\n\n\n\n

Step 1: Identify the Ions<\/h4>\n\n\n\n
    \n
  • Plumbic ion (Pb\u2074\u207a)<\/strong>: This is a lead ion with a +4 charge.<\/li>\n\n\n\n
  • Nitride ion (N\u00b3\u207b)<\/strong>: This is a nitrogen ion with a -3 charge.<\/li>\n<\/ul>\n\n\n\n

    Step 2: Total Charges<\/h4>\n\n\n\n

    We are told:<\/p>\n\n\n\n

      \n
    • There are 3 Pb\u2074\u207a ions<\/strong> \u2192 total positive charge = 3 \u00d7 (+4) = +12<\/strong><\/li>\n\n\n\n
    • There are 4 N\u00b3\u207b ions<\/strong> \u2192 total negative charge = 4 \u00d7 (\u22123) = \u221212<\/strong><\/li>\n<\/ul>\n\n\n\n

      Since +12 and \u221212 add to zero, the compound is electrically neutral<\/strong>, which is a requirement for any stable ionic compound.<\/p>\n\n\n\n

      Step 3: Write the Chemical Formula<\/h4>\n\n\n\n

      When writing ionic formulas:<\/p>\n\n\n\n

        \n
      1. The cation (positive ion)<\/strong> comes first: Pb<\/strong><\/li>\n\n\n\n
      2. The anion (negative ion)<\/strong> comes second: N<\/strong><\/li>\n\n\n\n
      3. The subscripts<\/strong> indicate how many of each ion are present, based on the ratio that balances charges.<\/li>\n<\/ol>\n\n\n\n

        So with 3 Pb\u2074\u207a and 4 N\u00b3\u207b, the formula is:<\/p>\n\n\n\n

        \n

        Pb\u2083N\u2084<\/strong><\/p>\n<\/blockquote>\n\n\n\n

        This is the simplest whole-number ratio of ions that results in a neutral compound.<\/p>\n\n\n\n

        Why Other Options Are Incorrect:<\/h4>\n\n\n\n
          \n
        • Options like [Pb4+]3[N3\u2212]4[Pb^{4+}]^3[N^{3-}]^4 describe the ions but not the chemical formula<\/strong>.<\/li>\n\n\n\n
        • \u201c4 N\u00b3\u207b 3 Pb\u2074\u207a\u201d is a ratio, not a proper formula.<\/li>\n\n\n\n
        • \u201cNone of these is correct\u201d is incorrect because Pb\u2083N\u2084 is<\/em> correct.<\/li>\n<\/ul>\n\n\n\n
          \n\n\n\n

          Final Answer: Pb\u2083N\u2084<\/strong> \u2705<\/h3>\n\n\n\n
