The highest energy electron in Zirconium (Zr) corresponds to the 4th energy level (n=4) with an angular momentum quantum number of l=3 (d-orbital), a magnetic quantum number ml ranging from -3 to 3, and a spin quantum number of ms=+1/2. This set of quantum numbers specifies the 4d subshell in which the electron resides.
The set of quantum numbers n=1, l=2, ml=0 cannot occur together to specify an orbital. This is because the quantum number l (azimuthal quantum number) ranges from 0 to n-1, meaning l cannot be greater than or equal to n.

The third quantum number is the magnetic quantum number, also known as the quantum number that specifies the orientation of an orbital in space. For a 3s orbital, the possible values of the magnetic quantum number range from -l to +l, where l is the azimuthal quantum number, which is 0 for an s orbital. Therefore, the third quantum number for a 3s2 electron in phosphorus is 0.

The quantum number set of the ground-state electron in helium, but not in hydrogen, is (1s^2) or (n=1, l=0, ml=0, ms=0). It indicates that the electron occupies the 1s orbital, which has a principal quantum number (n) of 1, an orbital angular momentum quantum number (l) of 0, a magnetic quantum number (ml) of 0, and a spin quantum number (ms) of 0.
A possible quantum number set for an electron in a ground-state helium atom could be n1, l0, m0, s1/2.
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.
The atomic number of potassium (K) is 19, and its electron configuration is [Ar] 4s¹. The valence electron of potassium is in the 4s orbital. Therefore, the correct set of four quantum numbers for this valence electron is: n = 4 (principal quantum number), l = 0 (angular momentum quantum number for s), m_l = 0 (magnetic quantum number), and m_s = +1/2 or -1/2 (spin quantum number, typically +1/2 for the single valence electron).
The quantum numbers for the 4d orbital are n=4, l=2, ml=-2, -1, 0, 1, 2, and ms=+1/2 or -1/2. The principal quantum number (n) represents the energy level, the azimuthal quantum number (l) represents the subshell, the magnetic quantum number (ml) represents the orientation of the orbital, and the spin quantum number (ms) represents the spin of the electron.
The highest energy electron in Zirconium (Zr) corresponds to the 4th energy level (n=4) with an angular momentum quantum number of l=3 (d-orbital), a magnetic quantum number ml ranging from -3 to 3, and a spin quantum number of ms=+1/2. This set of quantum numbers specifies the 4d subshell in which the electron resides.

There are several different quantum numbers for a given atom (principle quantum number, the angular quantum number, the magnetic quantum number, the spin quantum number, etc) .I assume you are looking for the Principle Quantum number, n, which is equal to the row (period) in the period table in which the element is situated.For helium, the principle quantum number is 1.i.e. n = 1As another example; the principle quantum number for potassium (K), n = 4.
Electrons cannot have the same set of quantum numbers as another electron in the same atom due to the Pauli exclusion principle. This means that no two electrons can have identical values for the principal quantum number (n), azimuthal quantum number (l), magnetic quantum number (m_l), and spin quantum number (m_s) simultaneously. For example, if one electron has the quantum numbers n=2, l=1, m_l=0, and m_s=+1/2, no other electron in the same atom can have those exact same values.
The set of quantum numbers n=1, l=2, ml=0 cannot occur together to specify an orbital. This is because the quantum number l (azimuthal quantum number) ranges from 0 to n-1, meaning l cannot be greater than or equal to n.
