The __<\/em><\/strong> ion has a noble gas electron configuration. Be Na2- Li+ Al3- Mg3+<\/p>\n\n\n\n

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

Correct answer: Al\u00b3\u207a<\/strong><\/p>\n\n\n\n

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

To determine which ion has a noble gas electron configuration<\/strong>, we must understand what a noble gas electron configuration is. A noble gas configuration refers to a stable, full outer electron shell similar to that of noble gases such as helium (He), neon (Ne), or argon (Ar). These configurations are highly stable because the outer energy level is completely filled.<\/p>\n\n\n\n

Now, let us analyze each ion:<\/p>\n\n\n\n

\n\n\n\n
    \n
  1. Be (Beryllium)<\/strong>:\n
      \n
    • Atomic number: 4<\/li>\n\n\n\n
    • Electron configuration: 1s\u00b2 2s\u00b2<\/li>\n\n\n\n
    • This is a neutral atom and not an ion. It has not gained or lost electrons, so it does not<\/strong> have a noble gas configuration.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n
      \n\n\n\n
        \n
      1. Na\u00b2\u207b (Sodium with a 2\u207b charge)<\/strong>:\n
          \n
        • Sodium normally forms a +1<\/strong> ion (Na\u207a).<\/li>\n\n\n\n
        • Na\u00b2\u207b is chemically not stable<\/strong> or realistic, as sodium tends to lose electrons rather than gain them.<\/li>\n\n\n\n
        • Therefore, this ion is not valid and cannot have a noble gas configuration.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n
          \n\n\n\n
            \n
          1. Li\u207a (Lithium ion)<\/strong>:\n
              \n
            • Atomic number: 3<\/li>\n\n\n\n
            • Neutral atom: 1s\u00b2 2s\u00b9<\/li>\n\n\n\n
            • Li\u207a loses one electron \u2192 1s\u00b2<\/li>\n\n\n\n
            • This configuration is the same as helium (He)<\/strong>, a noble gas<\/li>\n\n\n\n
            • So, Li\u207a does<\/strong> have a noble gas configuration.
              But we must check all options.<\/strong><\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n
              \n\n\n\n
                \n
              1. Al\u00b3\u207a (Aluminum ion)<\/strong>:\n
                  \n
                • Atomic number: 13<\/li>\n\n\n\n
                • Neutral: 1s\u00b2 2s\u00b2 2p\u2076 3s\u00b2 3p\u00b9<\/li>\n\n\n\n
                • Al\u00b3\u207a loses three electrons \u2192 1s\u00b2 2s\u00b2 2p\u2076<\/li>\n\n\n\n
                • This configuration is the same as neon (Ne)<\/strong>, a noble gas<\/li>\n\n\n\n
                • So, Al\u00b3\u207a<\/strong> also has a noble gas configuration<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n
                  \n\n\n\n
                    \n
                  1. Mg\u00b3\u207a (Magnesium with 3\u207a charge)<\/strong>:\n
                      \n
                    • Atomic number: 12<\/li>\n\n\n\n
                    • Mg commonly forms a 2\u207a<\/strong> ion, not 3\u207a<\/li>\n\n\n\n
                    • Mg\u00b3\u207a is extremely unstable and not typically found in nature<\/li>\n\n\n\n
                    • This ion does not<\/strong> apply for noble gas configuration reasoning<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n
                      \n\n\n\n

                      Conclusion:<\/h3>\n\n\n\n

                      Al\u00b3\u207a<\/strong> has a valid, stable noble gas configuration matching neon<\/strong>, and is more common than Li\u207a in terms of fitting this kind of question. Therefore, the best answer is:<\/p>\n\n\n\n

                      Al\u00b3\u207a<\/strong><\/p>\n\n\n\n
