(a) Fe+ \u00c3\u201a\u00c2 <\/p>\n\n\n\n

(b) Ni\u00c3\u201a\u00c2 <\/p>\n\n\n\n

(d) Cu2+\u00c3\u201a\u00c2 <\/p>\n\n\n\n

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

The correct answer is (c) Ni\u00b2\u207a<\/strong>.<\/p>\n\n\n\n

Explanation:<\/h3>\n\n\n\n
    \n
  1. Given Configuration<\/strong>:
    The electron configuration provided is:
    1s\u00b2 2s\u00b2 2p\u2076 3s\u00b2 3p\u2076 4s\u2070 3d\u2078<\/strong>. This means the 4s orbital is empty ((4s^0)), and the 3d subshell has 8 electrons ((3d^8)).<\/li>\n\n\n\n
  2. Understanding Electron Configurations<\/strong>:<\/li>\n<\/ol>\n\n\n\n
      \n
    • In neutral transition metals, electrons first fill the 4s orbital and then the 3d orbital.<\/li>\n\n\n\n
    • Upon ionization, electrons are removed first from the 4s orbital before the 3d orbital, because the 4s electrons are higher in energy for transition metals.<\/li>\n<\/ul>\n\n\n\n
        \n
      1. Analyzing the Choices<\/strong>:<\/li>\n<\/ol>\n\n\n\n
          \n
        • (a) Fe\u207a (Iron ion)<\/strong>:
          Neutral iron ((Fe)) has the configuration (1s\u00b2 2s\u00b2 2p\u2076 3s\u00b2 3p\u2076 4s\u00b2 3d\u2076).
          (Fe\u207a) would lose one electron, resulting in (1s\u00b2 2s\u00b2 2p\u2076 3s\u00b2 3p\u2076 4s\u00b9 3d\u2076), which does not match the given configuration.<\/li>\n\n\n\n
        • (b) Ni (Nickel)<\/strong>:
          Neutral nickel ((Ni)) has the configuration (1s\u00b2 2s\u00b2 2p\u2076 3s\u00b2 3p\u2076 4s\u00b2 3d\u2078).
          The 4s orbital is not empty in neutral nickel, so this does not match.<\/li>\n\n\n\n
        • (c) Ni\u00b2\u207a (Nickel ion)<\/strong>:
          Neutral nickel ((Ni)) loses 2 electrons to become (Ni\u00b2\u207a).
          The two electrons are removed from the 4s orbital, leaving (1s\u00b2 2s\u00b2 2p\u2076 3s\u00b2 3p\u2076 4s\u2070 3d\u2078).
          This matches the given configuration.<\/li>\n\n\n\n
        • (d) Cu\u00b2\u207a (Copper ion)<\/strong>:
          Neutral copper ((Cu)) has the configuration (1s\u00b2 2s\u00b2 2p\u2076 3s\u00b2 3p\u2076 4s\u00b9 3d\u00b9\u2070).
          Losing two electrons from (Cu) results in (1s\u00b2 2s\u00b2 2p\u2076 3s\u00b2 3p\u2076 4s\u2070 3d\u2079), not (3d\u2078).<\/li>\n<\/ul>\n\n\n\n
            \n
          1. Conclusion<\/strong>:
            The configuration (1s\u00b2 2s\u00b2 2p\u2076 3s\u00b2 3p\u2076 4s\u2070 3d\u2078) corresponds to Ni\u00b2\u207a<\/strong>, making (c)<\/strong> the correct answer.<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
