Question
Chemistry Question on Modern Periodic Law And The Present Form Of The Periodic Table
Metals having ns1 the valence electronic configuration:
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
Answer
are highly electropositive
Explanation
Solution
ns1 is the electronic configuration of I−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.
