- a)Least ionisation enthalpy on the left and highest negative electron gain enthalpy on the right
- b)Non-metallic character on the left and metallic character on the right
- c)High atomic radii on the left and small atomic radii on the right
- d)Highest electronegativity on the left and least electronegativity oh the right
Correct answer is option 'A'. Can you explain this answer?

Elements on the left side have lowest ionisation enthalpy due to which they can very easily lose electrons while the elements onthe right can accept electrons easily as they show highest negative electron gain enthalpy.

Ionization enthalpy and electron gain enthalpy:
- The alkali metals on the extreme left of the periodic table have the lowest ionization enthalpies, making it easier for them to lose electrons and become positively charged ions.
- The halogens on the extreme right have the highest negative electron gain enthalpies, making them highly reactive as they tend to gain electrons to achieve a stable electron configuration.
Non-metallic and metallic character:
- Alkali metals exhibit non-metallic character as they readily lose electrons to form positively charged ions.
- Halogens exhibit metallic character as they tend to gain electrons to achieve a stable electron configuration.
Atomic radii:
- Alkali metals have relatively high atomic radii due to the presence of more electron shells.
- Halogens have small atomic radii as they have a higher effective nuclear charge, pulling the electrons closer to the nucleus.
Electronegativity:
- Alkali metals have the lowest electronegativity as they readily lose electrons.
- Halogens have the highest electronegativity as they tend to gain electrons.
In conclusion, the extreme left (alkali metals) and extreme right (halogens) of the periodic table exhibit maximum chemical reactivity due to their properties of ionization enthalpy and electron gain enthalpy, non-metallic and metallic character, atomic radii, and electronegativity.
- The alkali metals on the extreme left of the periodic table have the lowest ionization enthalpies, making it easier for them to lose electrons and become positively charged ions.
- The halogens on the extreme right have the highest negative electron gain enthalpies, making them highly reactive as they tend to gain electrons to achieve a stable electron configuration.

In conclusion, the extreme left (alkali metals) and extreme right (halogens) of the periodic table exhibit maximum chemical reactivity due to their properties of ionization enthalpy and electron gain enthalpy, non-metallic and metallic character, atomic radii, and electronegativity.
