Understanding the table requires looking at the trends. Pauling’s values follow the periodic trends strictly:
| Group | 1 | 2 | 13 | 14 | 15 | 16 | 17 | | :--- | :---: | :---: | :---: | :---: | :---: | :---: | :---: | | | Li: 0.98 | Be: 1.57 | B: 2.04 | C: 2.55 | N: 3.04 | O: 3.44 | F: 3.98 | | Period 3 | Na: 0.93 | Mg: 1.31 | Al: 1.61 | Si: 1.90 | P: 2.19 | S: 2.58 | Cl: 3.16 | | Period 4 | K: 0.82 | Ca: 1.00 | Ga: 1.81 | Ge: 2.01 | As: 2.18 | Se: 2.55 | Br: 2.96 | | Period 5 | Rb: 0.82 | Sr: 0.95 | In: 1.78 | Sn: 1.96 | Sb: 2.05 | Te: 2.10 | I: 2.66 | tabla de pauling
Here is the (tabla de Pauling), showing values for the main chemical elements. Understanding the table requires looking at the trends
La electronegatividad es una propiedad química que describe la "fuerza" con la que un núcleo atómico tira de los electrones compartidos en un enlace. En la escala de Pauling, estos valores son relativos y no tienen unidades, variando generalmente desde hasta 4.0 (para el Flúor) . Tendencias en la Tabla Periódica En la escala de Pauling, estos valores son

Linus Pauling was an American chemist, biochemist, and peace activist. He is one of only two people to have been awarded a Nobel Prize in two different fields (Chemistry in 1954 and Peace in 1962). His work on the nature of the chemical bond revolutionized the field, and his electronegativity scale remains the standard in chemistry education today.
