Question

Which of the following pairs of elements is most likely to form an ionic bond?

Answer 1

Explanation:

A pair of elements will most likely form an ionic bond if one is a metal and one is a nonmetal. These types of ionic compounds are composed of monatomic cations and anions..

Hope it helps....

Answer 2

Cl and K elements are the pairs of elements that are most likely to form an ionic bond.

Explanation:

• Electrostatic attraction between a cation (metal ion) and an anion (non-metal ion) of equal size results in the formation of ionic compounds. If the size difference is such that the cation is tiny and the anion is extremely large, they create a more covalent connection.

• An ion can be a single charged atom or a small collection of charged atoms (molecule). Cl (non-metal) and K(metal) are the pairs of elements that are most likely to form an ionic bond.

• In this combination, metal ions (K) may give electrons, whereas non-metal (Cl) and thus can take electrons.  Ionic compounds will develop more easily between elements with relatively low ionization enthalpy and elements with relatively high negative electron gain enthalpy.
