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

💡 Solution & Explanation

The standard Pauling values are approximately: C (2.5), N (3.0), O (3.5), F (4.0), P (2.1), S (2.5), Cl (3.0). The elements with values $\ge 3.0$ are Nitrogen, Oxygen, Fluorine, and Chlorine. Therefore, exactly 4 elements meet this condition.
