How many cells are used to write any electronic configuration?
Answers
Answer:
To write electronic configuration 4 ceel use
The number of shells to be written in any electronic configuration is dependent on the total number of electrons present in an atom.
• According,to the Rutherford-Bohr model the electrons around the nucleus are arranged in different shells which are denoted by uppercase letters like K,L,M,N and so on.
• Each of these shells can obtain a specific number of electrons which is summarised by the formula 2n²,where 'n' is the principal quantum number.
• In this manner,
K shell can obtain 2 electrons.
L shell can obtain 8 electrons.
M shell can obtain 18 electrons.
And this,2n² series will go on untill the total number of electrons are obtained by these shells.
• Now,the number ranking (eg. K=1,L=2,M=3,so on) of the last shell which completes the obtaining process is the total number of shells which we need to write to denote the electronic configuration of an atom.
