Given :
Electronic configuration of an electron :
.
To Find :
The element having such an electronic configuration .
Solution :
We know , the sum of all the power of s and p in all the orbit gives total number of atoms in elements .
So , atomic number is :
![Z=2+2+(2+2+2)+2+(2+2+2)\\\\Z=18](https://img.qammunity.org/2021/formulas/mathematics/high-school/35rli12o1mqc1u2jra4w56t7yvamgf9zo5.png)
Since , the atomic number is 18 .
Therefore , the element is Argon .
Hence , this is the required solution .
