Question

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> If the difference in the maximum number of electrons between two consecutive shells is 10. What is the alphabetical representation of these shells?

Answer 1

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> Let the shells be n and n+1 (As they are consecutive shells)
Now, $2(n+1{)}^2$ - $2n^2=10$.
Solving this further, we get, $2n^2+4n+2-2n^2=10$.
This further solves to $4n=8$.
So, the shell required = 2 and (2+1) = 3.
The alphabetical representation will be L shell and M shell.
