Concept explainers
Interpretation:
The arrangement of elements in a standard periodic table has to be chosen from the given options.
Concept Introduction:
Periodic law states that if the elements are arranged in increasing order of
Location of an element in a periodic table can be given by the period number and the group number. The horizontal row in a periodic table where the elements are present is known as Period. The vertical column in a periodic table where the elements are present is known as Group.
