Electrons are arranged around the nucleus in the orbit , so that their orbits formed a shell which is called as electron shell or orbital.
The electron shell is labels as K , L , M , N, O, P , and Q in alphabets or 1,2,3,4,5,6 and 7 in numbers from inner most shell to outer shell . Inner shell must fill completely before electrons can be added to an outer shell
The chemical properties of the atom can determine by the partially filled electron which is present in the outer most shell .
The maximum number of electrons present in the each shell can be calculated by the following equation ,
Maximum number of electron in each shell = 2n^2
Where,
n – Shell number
For example if the shell number is 1 , the maximum number of electron present in the first ‘K ’ shell is 2(1)^2=2 .If the shell number is 2 , the maximum number of electron present in the second‘ L’ shell is 2 ( 2 )^ 2 = 8 .
If the atoms have 8 electrons in their outer most electron shell , atoms are more stable, and first electron shell is also more stable with two electrons.
The shell is further divided into sub-shell.Each shell is composed of one or more subshells, which are themselves composed of
atomic orbitals . For example, the first (K) shell has one subshell, called 1s ; the second (L) shell has two subshells, called 2s and 2p ; the third shell has 3s , 3p , and 3d ; the fourth shell has
4s , 4p , 4d and 4f ; the fifth shell has 5s , 5p ,
5d , and 5f.
Each subshell is constrained to hold 4 ℓ + 2 electrons at most, namely:
Each s subshell holds at most 2 electrons
Each p subshell holds at most 6 electrons
Each d subshell holds at most 10 electrons
Each f subshell holds at most 14 electrons
Each g subshell holds at most 18 electrons
