NEETChemistryClassification of Elements and Periodicity in Properties
In the given graph, a periodic property (( R ) ) is plotted against atomic numbers ( Z ) of the elements. Which property is shown in the graph and how is it correlated with reactivity of the elements?
Options
- AIonisation enthalpy in a group decrease reactivity decreases from ( a e ).
- BIonisation enthalpy in a group decreases reactivity increases from ( a e ).
- CAtomic radius in a group decrease reactivity decreases from ( a e ).
- DMetallic character in a group decrease reactivity increases from ( a e ).
Correct answer
B. Ionisation enthalpy in a group decreases reactivity increases from ( a e ).
Step-by-step solution
I.E. in a group decreases and reactivity increases.
