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.

Why is it impossible for an electron to have the quantum numbers n1 I1 mi0 ms-1?
An electron cannot have the quantum numbers ( n=1, \ell=1, m_\ell=0, m_s=-\frac{1}{2} ) because the principal quantum number ( n ) must be a positive integer and the azimuthal quantum number ( \ell ) must satisfy ( 0 \leq \ell < n ). Since ( n=1 ) allows only ( \ell=0 ), the specified ( \ell=1 ) is not permissible. Therefore, the set of quantum numbers violates the rules of quantum mechanics, making it impossible for an electron to possess them.
In many-electron atoms which quantum numbers specify the energy of an electron?
the quantum number n determines the energy of an electron in a hyrdogen atom.
Do quantum numbers define the energy states and the orbitals available to an electron?
Yes, quantum numbers define the energy states and the orbitals available to an electron. The principal quantum number (n) determines the energy level or shell of an electron, the azimuthal quantum number (l) determines the shape or orbital type, the magnetic quantum number (m) determines the orientation of the orbital, and the spin quantum number (+1/2 or -1/2) determines the spin state of the electron. Together, these quantum numbers provide a complete description of the electron's state within an atom.
What is a quantum number?
Four quantum numbers are used to describe electrons. The principle quantum number is the energy level of an electron. The angular momentum number is the shape of the orbital holding the electron. The magnetic quantum number is the position of an orbital holding an electron. The spin quantum number is the spin of an electron.
What are quantum number and what is the signifunent of each quantum number?
Quantum numbers are sets of numerical values that describe the unique quantum state of an electron in an atom. There are four main quantum numbers: the principal quantum number (n), which indicates the energy level and size of the orbital; the azimuthal quantum number (l), which defines the shape of the orbital; the magnetic quantum number (m_l), which specifies the orientation of the orbital in space; and the spin quantum number (m_s), which describes the intrinsic spin of the electron. Together, these quantum numbers provide a complete description of an electron's position and behavior within an atom, crucial for understanding atomic structure and electron configurations.

Quantum numbers are values used to describe various characteristics of an electron in an atom, such as its energy, angular momentum, orientation in space, and spin. These numbers are used to define the allowed energy levels and possible configurations of electrons in an atom.
Why is it impossible for an electron to have the quantum numbers n3 i1?
I am checking the Wikipedia article on "quantum number", and don't find a quantum number "i" for the electron. If you mean "l", it seems that "l" can be between 0 and n-1. So, for n = 3, l can be between 0 and 2. If this is what you mean, I don't see any reason that would forbid this particular combination.
What are the quantum numbers for the sevententh electron of Argon?
The quantum numbers for the seventeenth electron of Argon would be n=3 (principal quantum number), l=1 (azimuthal quantum number), ml=0 (magnetic quantum number), and ms= -1/2 (spin quantum number).
What electron could have quantum numbers n4l2?
The given quantum numbers ( n = 4 ) and ( l = 2 ) correspond to an electron in a 4d subshell. Here, ( n ) represents the principal quantum number, indicating the energy level, while ( l ) represents the angular momentum quantum number, corresponding to a d-orbital (since ( l = 2 ) for d). The possible magnetic quantum numbers ( m_l ) for ( l = 2 ) are -2, -1, 0, 1, and 2, indicating the various orientations of the orbital. Thus, any electron in the 4d subshell could have these quantum numbers, but you would need to specify ( m_l ) and the spin quantum number ( m_s ) to fully define the electron's state.
