Barium (Ba) has the atomic number 56, and its electron configuration is [Xe] 6s². The quantum numbers for its outermost electrons are: for the two 6s electrons, the principal quantum number (n) is 6, the azimuthal quantum number (l) is 0 (s orbital), the magnetic quantum number (m_l) is also 0, and the spin quantum number (m_s) can be +1/2 or -1/2 for each electron. Thus, the quantum numbers for the two 6s electrons in barium are (6, 0, 0, +1/2) and (6, 0, 0, -1/2).

How many quantum numbers are there in quantum theory?
There are four quantum numbers: principal quantum number (n), azimuthal quantum number (l), magnetic quantum number (m_l), and spin quantum number (m_s). These numbers describe different properties of an electron in an atom, such as energy level, shape of the orbital, orientation in space, and spin.
Why is it impossible for an electron to have the quantum numbers?
It is impossible for an electron to have certain quantum numbers due to the principles of quantum mechanics, particularly the Pauli exclusion principle. This principle states that no two electrons in an atom can have the same set of four quantum numbers, which describe their energy level, angular momentum, magnetic orientation, and spin. Additionally, quantum numbers must adhere to specific rules, such as the principal quantum number (n) being a positive integer and the azimuthal quantum number (l) being an integer between 0 and n-1. If quantum numbers violate these conditions, they cannot correspond to a valid electron state.
Names and symbols of the four quantum numbers required to define the energy of electrons in atoms?
The four quantum numbers are: Principal quantum number (n) - symbolized as "n" Azimuthal quantum number (l) - symbolized as "l" Magnetic quantum number (ml) - symbolized as "ml" Spin quantum number (ms) - symbolized as "ms"
