Which of the following pairs of elements would most likely combine to form a salt (ionic bond) ? rb + cl2 h2 + o2 p + i2 ne + he

Rb and Cl₂.

ExplanationMetals tend to transfer their electrons to nonmetals when the two react. They will produce two ions. As a result, bonds between a metal and a nonmetal tend to be ionic.Nonmetals tend to share electrons. As a result, bonds between two nonmetals tend to be covalent.Noble gas elements are stable. They seldom react with other elements or with other noble gases.Rb is a metal. Cl is a nonmetal. They tend to form ionic bonds.H and O are nonmetals. They tend to form covalent bonds.P and I are nonmetals. They tend to form covalent bonds.Ne and He are noble gases. They won't react under standard conditions.
