(2)
Interpretation:
The number of elements present in fifth period has to be given.
(3)
Interpretation:
The given elements has to be located in the periodic table and the group and period to which these elements belong has to be given.
(4)
Interpretation:
The given group of elements has to be located in the periodic table and their group numbers has to be given.
(5)
(a)
Interpretation:
The elements that consist of diatomic molecules are hydrogen, nitrogen, oxygen, fluorine, chlorine, bromine, iodine, astatine and element 117. The symbols of these elements has to be circled in the periodic table.
(b)
Interpretation:
A rule has to be devised to the periodic table that helps in remembering the elements consists of diatomic molecules.
