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

The correct answer is: (a) 0 1 1<\/strong><\/p>\n\n\n\n

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

To determine which p-orbital electron configuration obeys all three fundamental rules \u2014 the Aufbau Principle<\/strong>, Pauli Exclusion Principle<\/strong>, and Hund’s Rule<\/strong> \u2014 we need to evaluate each choice carefully.<\/p>\n\n\n\n

\n\n\n\n

1. Understanding the p-Orbitals<\/strong><\/h4>\n\n\n\n
    \n
  • A p-subshell has three orbitals<\/strong>: pxp_xpx\u200b, pyp_ypy\u200b, and pzp_zpz\u200b<\/li>\n\n\n\n
  • Each orbital can hold a maximum of two electrons<\/strong> with opposite spins<\/strong><\/li>\n\n\n\n
  • So the p-subshell can hold up to six electrons<\/strong> total<\/li>\n<\/ul>\n\n\n\n
    \n\n\n\n

    2. The Three Principles<\/strong><\/h4>\n\n\n\n
      \n
    • Aufbau Principle<\/strong>: Electrons fill orbitals in order of increasing energy. Lower energy orbitals fill before higher ones.<\/li>\n\n\n\n
    • Pauli Exclusion Principle<\/strong>: No two electrons in the same atom can have the same set of four quantum numbers. Therefore, each orbital can have at most two electrons, and they must have opposite spins.<\/li>\n\n\n\n
    • Hund’s Rule<\/strong>: When electrons occupy orbitals of equal energy (degenerate orbitals), one electron enters each orbital until all are half-filled before pairing begins. Electrons in singly occupied orbitals will have parallel spins.<\/li>\n<\/ul>\n\n\n\n
      \n\n\n\n

      3. Evaluate the Options<\/strong><\/h4>\n\n\n\n
        \n
      • (a) 0 1 1<\/strong>
        This means one electron in each of two orbitals and none in the third. This follows:\n
          \n
        • Hund\u2019s Rule: Yes, electrons occupy separate orbitals before pairing.<\/li>\n\n\n\n
        • Pauli Exclusion Principle: Yes, since no orbital has more than one electron.<\/li>\n\n\n\n
        • Aufbau Principle: Yes, electrons are filling the lowest energy p-orbitals.
          \u2713 This is correct.<\/strong><\/li>\n<\/ul>\n<\/li>\n\n\n\n
        • (b) 4 _ –<\/strong>
          Invalid. No orbital can have 4 electrons. This violates both Pauli Exclusion Principle and Aufbau Principle.
          \u2717 Incorrect.<\/strong><\/li>\n\n\n\n
        • (c) L 1 1<\/strong>
          This is not a valid numeric configuration. ‘L’ is not a number, so it’s ambiguous or invalid.
          \u2717 Incorrect.<\/strong><\/li>\n\n\n\n
        • (d) 1 4 1<\/strong>
          The second orbital has 4 electrons, which is impossible.
          \u2717 Incorrect.<\/strong><\/li>\n<\/ul>\n\n\n\n
          \n\n\n\n

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

          Only option (a) 0 1 1<\/strong> satisfies all three<\/strong> rules of electronic configuration.<\/p>\n\n\n\n
