The four quantum numbers are the principle quantum number, n , the angular momentum quantum number, l , the magnetic quantum number, ml , and the electron spin quantum number, ms .
The numerals, called principal quantum numbers, indicate energy levels as well as relative distance from the nucleus. A 1s electron occupies the energy level nearest the nucleus. A 2s electron, less strongly bound, spends most of its time farther away from the nucleus.
magnetic quantum number (m): Describes the orbital orientation of the electron in space. principal quantum number (n): Specifies the main energy level occupied by the electron. quantum numbers: Describe the location of an electron in an atom. spin quantum number (ms): Describes the spin for a given electron.
| Name | Symbol | Value examples |
|---|---|---|
| Principal quantum number | n | n = 1, 2, 3, … |
| Azimuthal quantum number (angular momentum) | ℓ | for n = 3: ℓ = 0, 1, 2 (s, p, d) |
| Magnetic quantum number (projection of angular momentum) | mℓ | for ℓ = 2: mℓ = −2, −1, 0, 1, 2 |
| Spin quantum number | ms | for an electron s = 12, so ms = − 12, + 12 |
Quantum numbers may be defined as a set of 4 numbers with the help of which we can get complete information about all the electrons in an atom, i.e. location, energy, the type of Orbital occupied, space and orientation of that orbital.
There are five 4d orbitals.
The three quantum numbers (n, l, and m) that describe an orbital are integers: 0, 1, 2, 3, and so on. The principal quantum number (n) cannot be zero. The allowed values of n are therefore 1, 2, 3, 4, and so on. The angular quantum number (l) can be any integer between 0 and n – 1.
The two unpaired electrons are in the outermost sublevel, 3p. Since the sublevel is 3p, we can see that the principal quantum number (n) = 3.
Lithium has 3 electrons, (z=3) . Principal quantum number for Lithium is n=1,2 n = 1 , 2 . Azimuthal quantum number for Lithium is calculated by, l=n−1 l = n − 1 . So, Azimuthal quantum number is l=0 .

For any atom, there are seven 5f orbitals. The f-orbitals are unusual in that there are two sets of orbitals in common use.
Wolfgang Pauli formulated the law stating that no two electrons can have the same set of quantum numbers.

Barium Atomic and Orbital Properties Barium atoms have 56 electrons and the electronic shell structure is [2, 8, 18, 18, 8, 2] with Atomic Term Symbol (Quantum Numbers) 1S0.
– The quantum numbers for iron are principal quantum number (n) is 4, azimuthal quantum number (l) = 2 for 3d –orbital, magnetic quantum number (m) is -2, -1, 0 , 1, 2 and spin quantum (s) number is either −12or+12 .
The correct quantum numbers for last electron of Copper (Cu) would be B. n=3,l=2,m=+2,s=−1/2. if I use B quantum numbers, it is the same with the last electron of zinc.
There are four quantum numbers: n, ℓ, mℓ, and ms. Each one is a particular factor in an equation describing a property of the electron. At this introductory level, the equations are not needed.
The quantum numbers for the valence electron in an atom of lithium are 𝑛 equals two, 𝑙 equals zero, 𝑚 sub 𝑙 equals zero, and 𝑚 sub 𝑠 equals positive one-half.
So the quantum numbers of carbon are 2, 1, 0, +1/2.
Explanation: The four quantum numbers for an atom refer to the state of the valence or outermost electron. For a potassium atom, the electron configuration is 1s22s22p63s23p64s1 , which means that n=4 .
Magnesium is located in period 3, group 2 of the periodic table and has an atomic number equal to 12 . In your case, the value l=0 corresponds to the s-subshell. You can thus say that no electrons share the quantum numbers l=0 and ml=1 , in a magnesium atom, or in any atom for that matter.
Thus, in phosphorous element, the last electron is present in 3p subshell which belongs to 3pz 3 p z orbital. It belongs to 3 shell, p subshell. So, it has n=3,ml=−1,ms=12 n = 3 , m l = − 1 , m s = 1 2 and l=1. Hence, the set of quantum numbers are n=3,ml=−1,ms=12 n = 3 , m l = − 1 , m s = 1 2 and l=1respectively.
For any atom, there are nine 5g orbitals.
Yes, the 5th energy level holds 5 sublevels and that last one would be 5g. Electrons add in energy order (Aufbau Principle) not energy level order.
