Question

reactivity quick check
which elements would react most easily with each other? (1 point)
an element with a high electronegativity and a second element with a high electronegativity
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

Explanation:

Elements react to achieve a stable electron - configuration. An element with high electronegativity has a strong attraction for electrons. An element with a single valence electron can easily lose that electron. They can form an ionic bond easily as the high - electronegativity element can gain the single valence electron from the other element. Elements with high electronegativity and other high - electronegativity elements may not react as easily as they both want to gain electrons. Elements with low reactivity or full shells are less likely to react.

Answer:

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