How many sub shells does n 4 have?
Four subFour sub-shells are associated with n = 4, which are s, p, d and f..
Why are shells named KLMN?
The names of the electron shells come from a fellow named Charles G. Barkla, a spectroscopist who studied the X-rays that are emitted by atoms when they are hit with high energy electrons. … This innermost shell is now called the K-shell, after the label used for the X-ray.
Why does the first shell only have 2 electrons?
There are at most two electrons in the first shell because of the Pauli Exclusion Principle, which says there can be only one electron with a given set of quantum values: only the spin can change, it can be -1/2 or +1/2. So that is two.
How many electrons can the outer shell hold?
eight electronsMost of the elements important in biology need eight electrons in their outermost shell in order to be stable, and this rule of thumb is known as the octet rule. Some atoms can be stable with an octet even though their valence shell is the 3n shell, which can hold up to 18 electrons.
Why outermost shell Cannot have more than 8 electrons?
The shells of an atom cannot accommodate more than 8 electrons, even if it has a capacity to accommodate more electrons. This is a very important rule called the Octet rule. According to this rule, atoms gain, loose or share electrons to achieve the stable configuration similar to the nearest noble gas.
How many electrons can the 5th energy level hold?
32 electronsThe fifth energy level contains: 5s (which holds 2 electrons), 5p (which holds 6), 5d (holds 10), and 5f (holds 14) for a total of 32 electrons. After that, the fifth, sixth, and seventh energy levels also have four sublevels each.
Can two electrons be in the same shell?
The state of a system is completely described by a complete set of quantum numbers. … The Pauli exclusion principle says that no two electrons can have the same set of quantum numbers; that is, no two electrons can be in the same state. This exclusion limits the number of electrons in atomic shells and subshells.
How many electrons are possible in all shells with n l 5?
Answer. For the 5s orbital, n = 5 and l =0, therefore (n + l) = 5. An s subshell has only one orbital and as an orbital can hold a maximum of two electrons, therefore the maximum number of electrons that would be present in the 5s orbital would be 2.
How many electrons in an atom can have the quantum numbers?
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.
Which element has 2 5 electrons per shell?

Why are there 32 electrons in the 4th Shell?
In my textbook, it says that the maximum number of electrons that can fit in any given shell is given by 2n². This would mean 2 electrons could fit in the first shell, 8 could fit in the second shell, 18 in the third shell, and 32 in the fourth shell.
How many electrons are present in the Subshell having MS value of for N 5?
Answer. As there are 4 sub shells, those will be :- s,p,d,f giving a total of = 1+3+5+7= 16 orbitals and 1 electrons for each orbital with ms= -1/2 and +1/2 each.. Thus there will be 16 such electrons.
Why is 3rd shell 8 or 18?
The third shell of an atom has 18 electrons only not 8 electrons. You might be confused because first the electrons of 4s are filled and then the 10 electrons of 3d shells are filled. They are filled because of the n-l rule. … So after filling the 3s and 3p subshell with 8 electrons, the next shell to fill is the 4s one.
Why are there 18 electrons in the third shell?
The 3rd subshell consists of an s orbital , a set of (3)p orbitals and a set of (5)d orbitals. Each orbital holds 2 electrons and you will indeed find that you can fir 18 electrons in. … This is because it is the maximum capacity of the 3rd shell and it doesn’t tell about the order in which the electrons are filled.
