For a better understanding about the electrode configuration in an atom , the teacher wrote shorthand notation `n l^(x)` on the blackboard .
Looking at this notation , what could be the probable questions that generate in the student's mind ? Write any two of them.

Explanation

1) What is `n l^(x)` method ?
2) Where does it use ?
3) What is meant by n , l and x ?
4) How can we use ` nl^(x)` method in the writing of electronic configuration of an atom ?
