Concept explainers
Interpretation:
The elements that are known as halogens and alkali metals are found in which group of the periodic table respectively 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.
