Pauli's exclusion principle

∙ 10y agoNo. Electrons must have a different set of quantum numbers. This is Pauli's exclusion principle. In chemistry we talk about orbitals for example 3p orbitals, (three of them 3px, 3py, 3pz). Each orbital is defined by the three quantum numbers n, l, and m. Each of these orbitals can contain a maximum of two electrons, these have different spin quantum numbers, s. This is an example of Pauli's exclusion principle.

The quantum mechanical model of the atom?
"The quantum mechanical model of the atom" is a pretty vague phrase, but basically it can be thought of as the set of solutions to the Schroedinger equation HΨ = EΨ . (Yeah, that looks like the world's stupidest equation with solution H = E, but what's important to understand is that H isn't a variable or number, it's an operator. That means we don't get a single E for all Ψ, we get a collection of Es each corresponding to a different function Ψ.)
How many outer electrons does Rb have?
It outermost electron in Krypton is 4s1 so the quantum number set is: n l ml ms 4 0 0 1/2 n= principal quantum number l- angular shapes of the lob ml- orientation of the lobe ms- magnetic spin of the lobe , which always alternates between the values 1/2 and -1/2 Note that the quantum number l is always zero for the s orbital because there are only one subshell.
What is the complete set of quantum numbers for the fifth electron added to a hydrogen ion?
A hydrogen ion is a proton, and that cannot bind more than 1 electron. For Boron, which has charge 5 on the nucleus the electrons are 1s2 2s2 2p1
Which set of symbols represents atoms with the same valence electrons in the same electron shell?
Sr, Sn, I
What is a quantum number set for Magnesium?
The quantum number for Sodium is this: 1s2 => n = 1 l= 0 m=0 s = +/- 1/2 2s2 => n=2 l=0 m= 0 s = +/- 1/2 2p6 => n = 2 ; l = 1 , m = -1 , 0 , +1 s = +/- 1/2 3s1 => n = 3 l=0 m=0 s = + 1/2
What is the quantum number set of the ground-state electron that is found in helium but not in hydrogen?
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.
What is the difference between two isotopes of an electron?
There is no difference. Electrons are subatomic particles and therefore identical.Added:In the same orbital, defined by one 'tri' set of quantum numbers (n, l, and ml ) the spin quantum number differs, the two values being ms = +1/2 and ms = -1/2, are each taken by one electron.
What is need of Spin quantum number?
The spin quantum number was created in the early twentieth century to account for the magnetic properties of the electron. It has only two possible values, +1/2 and -1/2, which indicates the two possible spin states of the electron. A single orbital can hold up to 2 electrons, which must have opposite spin states.
What is the quantum number set for Oxygen?
the quantum number for Mercury is 5,2,2,-1/2
What is the set of quantum number for 4d orbital?
n (principle quantum number) = 4 l (angular momentum quantum number) = 2 ml (magnetic quantum number) = -2, -1, 0, 1, or 2 ms (spin quantum number) = +1/2 or -1/2

Set of four quantum numbers for the final electron found in Cobalt Does anyone know how to find this answer or what is the answer?
(3,2,-1,-1/2)
Who gave the following statement ' No two electrons can have the same set of quantum number in the same atom'?
That's the Pauli Exclusion Principle, so most likely Wolfgang Pauli.
What is the set of numbers of quantum numbers?
Assuming you mean the set of quantum number describing the VALENCE electrons of aluminum, they would ben = 3l = 1ml = -1s = +1/2Of course, since Al has only 1 p electron, ml could also have been 0 or +1 and s could have been -1/2
What does the third quantum number (l) describe?
The specific orbital within a sublevel- apex
Who said that no two electron in atom can have the same set of four quantum number?
Werner Karl Heisenberg To Quote "It is impossible to define, with exact Precision And Certanty, the speed and momentum of an electron, or indead any other sus atomic particle which moves at the speed of light"
