Question

Quizplus · Accepted Answer

In binary ionic compounds, cations are formed by the elements that have a lower electronegativity value. In set B, calcium, chromium, and lead all have lower electronegativity values relative to their corresponding anionic partners. Therefore, all elements in set B tend to form cations in binary ionic compounds.
