Expert Answer:

If the atomic number is given from the electronic configuration we can find the poasition of the element.
 
Example:
 
Carbon (6)
 
Electronic configuration: (2,4)
 
No. of valence electrons gives the group number and no of shells gives period.
 
So it corrosponds to group 4 and period 2.
