Question

Kisi kaksha Mein electron ka nirdharan kis formula dwara Hota Hai​

Answer 1

Answer:

2n²

Explanation:

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

Formula Explaination:-

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
