Answer 1

Electronegativity generally decreases with increasing atomic radius and increases with the number of valence electrons due to increased effective nuclear charge. Therefore, the element that would have the lowest electronegativity is:

**an element with a small number of valence electrons and a large atomic radius.**

This is because the large atomic radius means that the valence electrons are farther from the nucleus, making it less effective at attracting electrons.
