Question

State the maximum capacity of various shells to accommodate electrons

Answer 1

The maximum capacity of various Shells to accommodate electrons of an Atom are derived by the formula 2(n²).

For example:- The maximum number of electrons which can accommodate in Shell 1 or Shell 'K' is 2(1)² = 2*1 = 2

2nd Shell 'L' can accommodate electrons that are = 2(2)² = 2*4 = 8

3rd Shell 'M' can accommodate electrons that are = 2(3)² = 2*9 = 18

4th Shell 'N' can accommodate electrons that are = 2(4)² = 2*16 = 32....

But there is a rule that the outermost shell of an Atom can accomodate only 8 electrons at the most or less..

IF more electrons are there, they accomodate by making a new shell..

For eg- Calcium is an element with 20 electrons..

It's first shell k will have 2 electrons, 2nd shell L will have 8 electrons, the third shell M will have to accommodate only 8 electrons, rest left over 2 electrons would reside by forming a new shell N which would hold these 2 electrons..
