A) are strong oxidising agents
B) are highly electronegative
C) are highly electropositive
D) have a first ionisation potential of more than 10 eV/atom
Correct Answer: C
Solution :
\[n{{s}^{1}}\] is the electronic configuration of \[\text{I}-\text{A}\] group metals which are known as alkali metals. Alkali metals have a strong tendency to donate electrons and forms +ve ions means have highly electropositive character.
