What is the maximum number of electron which can be accommodated in N shell |
|
Answer» 18 The number of electrons that can be accomodated in a shell is determined by the formula "2n^2"(2* square of n) , where n is the position of the shell (quantum number) .N shell is at 4th position (K-1, L-2 , M-3 ,N-4).So number of electrons in N shell = 2n^2 = 2*4^2 =2*16 = 32. Thus 32 electrons can be accomodated in N shell. 32 2 |
