What is the formula for an ionic compound made of aluminum and nitrogen? A. Al3N2 B. Al2N4 C. Al3N3 D. AlN E. none of these choices is correct<\/p>\n\n\n\n

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

Correct Answer: D. AlN<\/strong><\/p>\n\n\n\n

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

To determine the correct formula for an ionic compound made of aluminum and nitrogen<\/strong>, we need to understand the charges of the ions each element forms and then balance those charges to form a neutral compound.<\/p>\n\n\n\n

Step 1: Determine the Ions<\/h4>\n\n\n\n
    \n
  • Aluminum (Al)<\/strong> is a metal in Group 13 of the periodic table. It loses three electrons<\/strong> to achieve a stable electron configuration, forming a +3 cation<\/strong>: Al\u2192Al3++3e\u2212\\text{Al} \\rightarrow \\text{Al}^{3+} + 3e^-<\/li>\n\n\n\n
  • Nitrogen (N)<\/strong> is a nonmetal in Group 15. It gains three electrons<\/strong> to complete its octet, forming a -3 anion<\/strong>: N+3e\u2212\u2192N3\u2212\\text{N} + 3e^- \\rightarrow \\text{N}^{3-}<\/li>\n<\/ul>\n\n\n\n

    Step 2: Balance the Charges<\/h4>\n\n\n\n

    When forming an ionic compound, the total positive charge must balance the total negative charge. Since Al\u00b3\u207a<\/strong> and N\u00b3\u207b<\/strong> have charges of equal magnitude but opposite sign, only one aluminum ion is needed for one nitrogen ion<\/strong> to achieve charge neutrality: Al3++N3\u2212\u2192AlN\\text{Al}^{3+} + \\text{N}^{3-} \\rightarrow \\text{AlN}<\/p>\n\n\n\n

    This gives the formula AlN<\/strong>.<\/p>\n\n\n\n

    Step 3: Why the Other Options Are Incorrect<\/h4>\n\n\n\n
      \n
    • A. Al\u2083N\u2082<\/strong> implies an imbalance: 3(3+) = +9, 2(3\u2212) = \u22126 \u2192 net charge \u2260 0.<\/li>\n\n\n\n
    • B. Al\u2082N\u2084<\/strong> implies: 2(3+) = +6, 4(3\u2212) = \u221212 \u2192 net charge \u2260 0.<\/li>\n\n\n\n
    • C. Al\u2083N\u2083<\/strong> implies: 3(3+) = +9, 3(3\u2212) = \u22129 \u2192 net charge = 0, but this simplifies to AlN (a 1:1 ratio).<\/li>\n\n\n\n
    • E. None of these choices<\/strong> is incorrect because D (AlN)<\/strong> is<\/em> the correct choice.<\/li>\n<\/ul>\n\n\n\n

      Conclusion<\/h4>\n\n\n\n

      The correct formula for the ionic compound formed between aluminum and nitrogen is AlN<\/strong>, which reflects the 1:1 ratio needed to balance the +3 and \u22123 charges of the ions.<\/p>\n\n\n\n
