Question

Which element would have the lowest electronegativity

An element with a small number of valence electrons and small atomic radius

An element with a large number of valence electrons and small atomic radius

An element with a small number of valence electrons and large atomic radius

An element with a large number of valence electrons and large atomic radius

Which one is correct

Answer 1

An element with a large number of valence electrons and large atomic radius would have the lowest electronegativity. Electronegativity generally increases as the number of valence electrons and atomic radius decrease.
