## What is the maximum number of electrons in an atom that can have N 4 and L 2?

n=4,l=2 means that is 4d orbital so it can accommodate maximum 10 Jun 12, 2017 Therefore, a maximum number of 10 electrons can share these two quantum numbers in an atom. n = 6, 72. This means each orbital will contain two electrons.

## How many electrons are possible in all Subshells with N +L 4?

In an atom, both 4s (n = 4, l = 0) and (n = 3, l = 1) orbitals can have n + l =4. Since four orbitals are involved, they can have maximum of eight electrons.

## How many possible orbitals are there for N 4?

For n = 3 there are nine orbitals, for n = 4 there are 16 orbitals, for n = 5 there are 5^{2} = 25 orbitals, and so on. To calculate the maximum number of electrons in each energy level, the formula 2n^{2} can be used, where n is the principal energy level (first quantum number).

## What is the maximum number of electrons in an atom with N 4?

A total of 32 electrons can have the n = 4 quantum number. Only one orbital of a shell like p, d or f can have = +1 value. An orbital can have a maximum of two electrons.

## Why is 3rd shell 8 or 18?

Each shell can contain only a fixed number of electrons, up to two electrons can hold the first shell, up to eight (2 + 6) electrons can hold the second shell, up to 18 (2 + 6 + 10) can hold the third shell and so on.

## What is full form of KLMN?

klmn are shells. k is 1st shell and k=1,2,3 l is 2nd shell and l=0,1,2,3. m is 3rd shell and m=-1/2,1/2. n is 4th shell.

## Why do electron shells start at K?

The names of the electron shell were given by a spectroscopist named Charles G Barkla. He named the innermost shell has k shell because he noticed that the X-rays emitted two types energies. He noticed that K type X-rays emitted the highest energy. Therefore, he named the innermost shell as the K shell.

## Why does the third shell have 8 electrons?

There are certain rules for arranging atoms in shells 1) Maximum number of electrons in a shell is given by the formula 2n^2. 2) The outermost ( valence) shell can accomodate only 8 electrons.
