Consider the following statements:
(i) The discovery of inert gases later on did not disturb Mendeleev's arrangement.
(ii) In the present periodic table, periodicity in the properties of elements is related to the periodicity in their electronic configurations.
Which of these statement(s) is/are correct?
(i) The discovery of inert gases later on did not disturb Mendeleev's arrangement.
(ii) In the present periodic table, periodicity in the properties of elements is related to the periodicity in their electronic configurations.
Which of these statement(s) is/are correct?
View answer and explanation
Correct option: C
Both (i) and (ii)
Option C (Both (i) and (ii)) is correct because the discovery of inert gases fit into Mendeleev's table without disrupting it, and the modern periodic table's properties are linked to electronic configurations.
