`Cu(g)overset(+e^(-))rarrCu^(+)(g)`. Write the set of quantum numbers for the electron released in this process. 

Explanation

`underset("(2,8,18,1)")(Cu(g)) overset(-e^(-))rarrunderset("(2,8,18)")(Cu^(+)(g))`
The electrons released is from s-orbital of `4^(th)` shell. The set of quantum numbers is `(4, 0, 0, +1//2)`
