Which elements would react most easily with each other?

Question

(1 point)
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
an element with a high electronegativity and an element
with low reactivity
an element with a high electronegativity and an element
with a single valence electron

Answer 1

The pair that would react most easily with each other is:

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

This is because the element with a high electronegativity (such as a nonmetal) would readily attract the single valence electron from the other element (typically a metal), leading to a strong ionic bond and a reaction between the two.
