Question

reactivity quick check
which elements would react most easily with each other? (1 point)
an element with a high electronegativity and an element with a single valence electron
an element with a high electronegativity and an element with low reactivity
an element with a high electronegativity and an element with a full shell of electrons
an element with a high electronegativity and a second element with a high electronegativity

Explanation:

Electronegativity is the ability of an atom to attract electrons. An element with a high electronegativity wants to gain electrons. An element with a single - valence electron can easily lose that electron. So, they are likely to react with each other. An element with low reactivity won't react easily. An element with a full shell of electrons is stable and unreactive. Two elements with high electronegativities won't react as easily as they both want to gain electrons and there is no easy electron - transfer mechanism.

Answer:

an element with a high electronegativity and an element with a single valence electron
