Answer 1

K,L, M, N, O- are the shells present (orbitals) in an atom. Whereas s,p,d,f - are the sub-shells present in each of the K,L,M,N,O -shells. K-Shell contains only s- subshell. L-Shell contains s, p-subshells. M-Shell contains s,p,d-subshells. N-Shell contains s,p,d,f-subshells.

Answer 2

Hey Mate
________________________________________________________________________
****Each Shell Contains A fixed No. Of Electrons

1.The first shell can hold up to two electrons,

2.the second shell can hold up to eight (2 + 6) electrons,

3.the third shell can hold up to 18 (2 + 6 + 10) and so on.

The general formula is 2n^2
The electrons in the outermost is Valence Shell..

***The s,p,d,f, notations are for orbitals of electrons and depend on l-values

where l= orbital angular momentum

A n th shell can have subshells having l = 0,1,2…(n- 1)

l=o is called s orbital

l=1 is …p -orbital

l=2 is …..d-orbital

the 2.n^2 electrons are subdivided in these orbitals.

for example

For N th shell- the principal quantum no. n= 4

the total no. of electron can be= 2. 4^2 = 32

then l= 0, 1, 2, 3 only

s, p, d, f subshells or orbitals

and they can have (2.l +1) no. of electrons

s state - max. 2 electrons - they obey pauli exclusion principal

p-state - 6 electrons

d- state- 10 electrons

f -state - 14 electrons
