Just as the way we locate a point on graph as (x, y), can we locate an element as (group number, period)?

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.
