Four quantum numbers are required to completely specify a single atomic orbital: principal quantum number (n), azimuthal quantum number (l), magnetic quantum number (m), and spin quantum number (s). These numbers describe the size, shape, orientation, and spin of the atomic orbital, respectively.
The four quantum numbers for Bromine (Z = 35) are: Principal quantum number (n): 4 Azimuthal quantum number (l): 0 Magnetic quantum number (ml): 0 Spin quantum number (ms): +1/2 or -1/2
How are electrons arranged in the quantum mechanical model of an atom
The principal quantum number (n = 1, 2, 3, 4, …) denotes the eigenvalue of Hamiltonian (H), i.e. the energy, with the contribution due to angular momentum (the term involving J2) left out. This number therefore has a dependence only on the distance between the electron and the nucleus (i.e., the radial coordinate, r). The average distance increases with n, and hence quantum states with different principal quantum numbers are said to belong to different shells.The azimuthal quantum number (ℓ = 0, 1, …, n − 1) (also known as the angular quantum number or orbital quantum number) gives the orbital angular momentum through the relationL2 = ħ2 ℓ (ℓ + 1). In chemistry, this quantum number is very important, since it specifies the shape of an atomic orbital and strongly influences chemical bonds and bond angles. In some contexts, "ℓ= 0" is called an s orbital, "ℓ = 1" a p orbital, "ℓ = 2" a d orbital, and "ℓ = 3" an f orbital.The magnetic quantum number (ml = −ℓ, −ℓ + 1, …, 0, …, ℓ − 1, ℓ) yields the projection of the orbital angular momentum along a specified axis. Lz = mℓħ.The spin projection quantum number (ms = ±½), is the intrinsic angular momentum of the electron or nucleon. This is the projection of the spin s = ½ along the specified axis.
Any combination of quantum numbers that violates the Pauli exclusion principle is not possible. For example, having two electrons in the same orbital with all four quantum numbers (n, l, ml, ms) being the same is not allowed.

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.

Quantum numbers can be defined as a number that occurs in the hypothetical expression for the value of some quantized property of a subatomic particle, atom, or molecule and can only have certain integral or half-integral values.
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.
The four quantum numbers for a magnesium (Mg) atom, which has an atomic number of 12, describe the electron configuration of its valence electrons. The configuration is 1s² 2s² 2p⁶ 3s². The quantum numbers for the outermost electrons (3s²) are: n = 3 (principal quantum number), l = 0 (azimuthal quantum number for s-orbital), m_l = 0 (magnetic quantum number), and m_s = +1/2 or -1/2 (spin quantum number). Thus, for one of the 3s electrons, the quantum numbers would be (3, 0, 0, +1/2) or (3, 0, 0, -1/2) for the paired electron.
