What? Why does it have a question mark it makes no sense because there isn’t any options and you didn’t explain what the question is about.
Group 1 elements (usually called alkali metals) are not very electronegative and have small ionization energies due to that. The reason why they are not very electronegative is that they really want to loose their one valence electron so that they can have a noble gas electron configuration (completed octet).
