Quantum number of Oxygen<\/p>\n\n\n\n

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

Oxygen (O) has an atomic number of 8, which means it has 8 electrons. The quantum numbers for these electrons describe their positions and energy levels within an atom. Each electron is described by four quantum numbers: principal quantum number ((n)), azimuthal quantum number ((l)), magnetic quantum number ((m_l)), and spin quantum number ((m_s)).<\/p>\n\n\n\n

    \n
  1. Principal Quantum Number ((n))<\/strong>: This number indicates the energy level and distance of the electron from the nucleus. For oxygen, the electrons are arranged in energy levels. The first energy level (K shell) has 2 electrons ((n=1)), and the second energy level (L shell) has the remaining 6 electrons ((n=2)).<\/li>\n\n\n\n
  2. Azimuthal Quantum Number ((l))<\/strong>: This number indicates the shape of the orbital. For (n=1), (l=0) (s orbital), and for (n=2), the possible values of (l) are 0 (s) and 1 (p). The first 2 electrons occupy the (1s) orbital (where (l=0)), while the next 6 electrons occupy the (2s) and (2p) orbitals. The configuration is (2s^2 2p^4).<\/li>\n\n\n\n
  3. Magnetic Quantum Number ((m_l))<\/strong>: This number indicates the orientation of the orbital. For (l=0) (s orbital), (m_l) can only be 0. For (l=1) (p orbital), (m_l) can be -1, 0, or +1, corresponding to the three p orbitals: (p_x), (p_y), and (p_z).<\/li>\n\n\n\n
  4. Spin Quantum Number ((m_s))<\/strong>: This number describes the spin of the electron, which can be +1\/2 or -1\/2. Each orbital can hold two electrons with opposite spins.<\/li>\n<\/ol>\n\n\n\n

    For oxygen, the distribution of electrons and their quantum numbers is:<\/p>\n\n\n\n

      \n
    • 1st electron: (n=1), (l=0), (m_l=0), (m_s=+\\frac{1}{2}) (1s)<\/li>\n\n\n\n
    • 2nd electron: (n=1), (l=0), (m_l=0), (m_s=-\\frac{1}{2}) (1s)<\/li>\n\n\n\n
    • 3rd electron: (n=2), (l=0), (m_l=0), (m_s=+\\frac{1}{2}) (2s)<\/li>\n\n\n\n
    • 4th electron: (n=2), (l=0), (m_l=0), (m_s=-\\frac{1}{2}) (2s)<\/li>\n\n\n\n
    • 5th electron: (n=2), (l=1), (m_l=-1), (m_s=+\\frac{1}{2}) (2p)<\/li>\n\n\n\n
    • 6th electron: (n=2), (l=1), (m_l=0), (m_s=-\\frac{1}{2}) (2p)<\/li>\n\n\n\n
    • 7th electron: (n=2), (l=1), (m_l=+1), (m_s=+\\frac{1}{2}) (2p)<\/li>\n\n\n\n
    • 8th electron: (n=2), (l=1), (m_l=+1), (m_s=-\\frac{1}{2}) (2p)<\/li>\n<\/ul>\n\n\n\n

      In summary, the quantum numbers of oxygen’s electrons define their arrangement in orbitals and contribute to its chemical properties.<\/p>\n","protected":false},"excerpt":{"rendered":"
