Answer 1

The pair of elements most likely to form monatomic ions based on electronegativity is Cl and Na.

Step-by-step explanation:

The pair of elements that is most likely to form monatomic ions based on electronegativity is Cl and Na.

When an atom gains or loses electrons to achieve a stable electron configuration, it forms an ion. The ion formed can be either positively charged (cation) or negatively charged (anion). Electronegativity is the measure of an atom's ability to attract electrons in a chemical bond.

In this case, Cl has a higher electronegativity than Na. Chlorine (Cl) needs one more electron to achieve a stable electron configuration, so it will gain an electron and form a negatively charged Cl- ion. Sodium (Na) has a lower electronegativity and will lose one electron to achieve a stable electron configuration, forming a positively charged Na+ ion. Therefore, Cl and Na are most likely to form monatomic ions.
