Understanding the table requires looking at the trends. Pauling’s values follow the periodic trends strictly:
The Tabla de Pauling is a fundamental tool in chemistry that helps us understand the behavior of atoms in molecules. By understanding electronegativity and how to read the Pauling Electronegativity Scale, you'll be better equipped to predict chemical reactivity, identify molecular shape, and analyze chemical bonds. While the scale has its limitations, it remains a valuable resource for chemists and students alike. tabla de pauling

Aportación de Pauling: Uso de la tabla de electronegatividad
The most important use of the Pauling Table is predicting the type of bond formed between two atoms. This is calculated using the difference in electronegativity ($\Delta \chi$).
