Electronegativity is a measure of an atom's ability to attract and hold onto electrons. In general, electronegativity decreases with increasing atomic radius and increases with increasing number of valence electrons.
Considering the options:
A: An element with a large number of valence electrons and a large atomic radius - This would likely have a relatively high electronegativity due to the large number of valence electrons.
B: An element with a small number of valence electrons and a small atomic radius - This element would likely have higher electronegativity because of the small atomic radius, allowing for a stronger attraction to the nucleus.
C: An element with a large number of valence electrons and a small atomic radius - This element would tend to have a high electronegativity due to the small radius and many valence electrons.
D: An element with a small number of valence electrons and a large atomic radius - This element would likely have the lowest electronegativity because a large atomic radius reduces the attraction between the nucleus and the valence electrons, and a small number of valence electrons indicates a less tendency to gain electrons.
Therefore, the correct answer is **D**: an element with a small number of valence electrons and a large atomic radius would have the lowest electronegativity.
