Sistema de Nomenclatura Stock

La nomenclatura Stock agrega números romanos entre paréntesis al final del nombre del elemento para indicar su valencia o estado de oxidación. Esto es especialmente útil cuando un elemento puede presentar diferentes estados de oxidación al combinarse con oxígeno.

Cuando un elemento tiene un único número de oxidación, se omite el paréntesis con el número romano. Por ejemplo, en Na₂O (óxido de sodio), el sodio siempre tiene valencia +1, por lo que no necesita especificarse. En cambio, para el mercurio que tiene dos posibles valencias, tenemos Hg₂O (óxido de mercurio (I)) y HgO (óxido de mercurio (II)).

El azufre y el cloro son ejemplos perfectos de elementos con múltiples estados de oxidación. El azufre forma SO (óxido de azufre (II)), SO₂ (óxido de azufre (IV)) y SO₃ (óxido de azufre (VI)). El cloro forma cuatro óxidos diferentes: Cl₂O, Cl₂O₃, Cl₂O₅ y Cl₂O₇, con estados de oxidación I, III, V y VII respectivamente.

💡 ¡Atención! Algunos elementos se nombran usando su nombre en otro idioma diferente al español, no su nombre común. Este detalle es crucial para nombrar correctamente los compuestos.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.
