How many electrons are present in 11na?
We know that the atomic number of sodium is 11. This tells us that sodium has 11 protons and because it is neutral it has 11 electrons.
How many electrons can have the values n 2 L 1 and S ½ in the configuration?
The orbital having n =2 and l=1 is 2p. Since 2p has three lobes and here there are three electrons a maximum of three electrons can have the above values.
What is the maximum number of electrons that can have the quantum numbers n 3 l 2 ml 2?
10 electrons
Therefore, a maximum number of 10 electrons can share these two quantum numbers in an atom.
How many electrons protons and neutrons are present in 23 11na?
Protons in Na = 11. Electrons = Same as that of protons i.e. 11. Neutrons = Mass Number – Atomic Number = 23- 11= 12.
What is the electronic configuration of 23?
Electronic Configuration of First 30 Elements with Atomic Numbers
Atomic Number | Name of the Element | Electronic Configuration |
---|---|---|
23 | Vanadium (V) | [Ar] 3d3 4s2 |
24 | Chromium (Cr) | [Ar] 3d5 4s1 |
25 | Manganese (Mn) | [Ar] 3d5 4s2 |
26 | Iron (Fe) | [Ar] 3d6 4s2 |
Can an electron have the quantum number n 1 L 2?
Yes, it is possible to have two electrons with the same n, l, and ml. The spin of one electron must be +1/2 while the spin of the other electron must be -1/2. There are three subshells in principal quantum level n=3.
How many electrons in an atom can have the following quantum numbers n 4 L 2?
The quantum numbers n = 4 and l = 2 correspond to 4d subshell. It can accommodate 10 electrons.
What is the maximum number of electrons in an atom that can have quantum numbers n 4 ml =+ 1?
There are three orbitals having me=+1. Thus maximum number of electrons in them will be 3×2=6.
What is the maximum number of electrons in an atom that can have the following quantum numbers n 5 l 3 ml 2?
2 electrons
Answer and Explanation: In this case only 2 electrons can exist with the quantum numbers n=5 , l=3 and mz=3 m z = 3 respectively.
How many electrons can have the following set of quantum numbers?
Only one electron in a given atom can have the set of quantum numbers given in the question.
What is the maximum number of electrons with the quantum numbers n 3 and ML 1?
Since each orbital can hold a maximum of two electrons, the number of electrons that can share the two quantum number n=3 and ml=−2 will be equal to 2 , each having opposite spin.
How many electrons can share a quantum number n = 3?
Since each orbital can hold a maximum of two electrons, the number of electrons that can share the two quantum number n = 3 and ml = −2 will be equal to 2, each having opposite spin. n = 3,l = 2,ml = − 2,ms = − 1 2 This set describes an electron located on the third energy level, in the 3d-subshell, in the 3dz2 orbital, and having spin down.
How many quantum numbers does it take to define an orbital?
electrons in an orbital is arbitrarily assigned an squantum number of +1/2, the other is assigned an squantum number of -1/2. Thus, it takes three quantum numbers to define an orbital but four quantum numbers to identify one of the electrons that can
What is the spin quantum number of an electron?
Finally, the spin quantum number, ms, which tells you the spin of the electron, can only have two possible values, − 1 2 for spin-down and + 1 2 for spin-up. You can thus say that the quantum number set given to you describes an electron
What are the rules for the combination of quantum numbers?
Rules Governing the Allowed Combinations of Quantum Numbers. 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.
