Question

Which of the following combinations of ions are most likely to bind, forming molecules?

A) anion and anion
B) anion and cation
C) cation and cation
D) none of these

Answer 1

An anion and cation are the most likely combination of ions to bind and form molecules.

Step-by-step explanation:

The most likely combination of ions to bind and form molecules is anion and cation (option B). An anion is a negatively-charged ion, and a cation is a positively-charged ion. When these oppositely charged ions come together, they form an ionic bond, which results in the formation of a molecule. For example, sodium chloride (NaCl) is formed when a sodium cation (Na+) binds with a chloride anion (Cl-).
