Just as the way we locate a point on graph as (x, y), can we locate an element as (group number, period)?
Asked by adipadmakarri | 05 Dec, 2020, 06:41: PM
Expert Answer
Yes, we can locate the element from the group and period.
 
Example:
 
Element that belongs to the 2nd group and 3rd period is magnesium.
 
Element that belongs to the group 14 and period 2 is carbon.
 
So from group number and period number we can locate the element in the periodic table.
