The Allred-Rochow scale defines electronegativity based on the electrostatic force exerted by the nu — Periodic Table and Periodicity Chemistry Question

💡 Solution & Explanation

The Allred-Rochow scale calculates electronegativity using the effective nuclear charge ($Z_{eff}$) and the covalent radius ($r_{cov}$), expressing the electrostatic force of attraction felt by an electron at the periphery of the atom. The formula involves $Z_{eff} / r_{cov}^2$.
