The correct answer is: an element with a high electronegativity and an element with a single valence electron.

The element with the lowest electronegativity would be an element with a large number of valence electrons and a large atomic radius. This is because electronegativity is the tendency of an atom to attract electrons towards itself in a covalent bond. Elements with a large number of valence electrons have a strong positive charge in the nucleus, which attracts electrons less strongly. Similarly, elements with a large atomic radius have a weaker attraction for electrons because the electrons are further away from the nucleus. Therefore, the combination of a large number of valence electrons and a large atomic radius leads to a lower electronegativity.

The correct answer is: an element with a large number of valence electrons and a small atomic radius.

The correct answer is: Elements with lower electronegativity are more reactive than elements with higher electronegativity.
