Consider the elements , and . Exactly how many of these specific elements possess a standard Pauling — Periodic Table and Periodicity Chemistry Question

💡 Solution & Explanation

On the Pauling scale, the accepted values are: Fluorine ($4.0$), Oxygen ($3.5$), Nitrogen ($3.0$), and Chlorine ($3.0$). Only Fluorine and Oxygen have values that are strictly greater than $3.0$. Therefore, exactly 2 elements meet this criteria.
