Elementos Químicos y sus Valencias

Los elementos químicos se dividen en dos grandes grupos: metales y no metales. Cada uno tiene un símbolo químico único (como una especie de "nombre corto") y diferentes valencias que indican cómo se pueden combinar con otros elementos.

Los no metales incluyen elementos súper importantes como el hidrógeno (H), oxígeno (O) y carbono (C). Fíjate que muchos tienen valencias negativas y positivas, lo que significa que pueden "dar" o "recibir" electrones dependiendo de con qué se combinen.

Los metales como el hierro (Fe), cobre (Cu) y oro (Au) suelen tener valencias positivas. Los metales del grupo 1 (litio, sodio, potasio) siempre tienen valencia +1, mientras que los del grupo 2 (magnesio, calcio) siempre tienen valencia +2.

Truco clave: Los elementos del mismo grupo (columna) en la tabla periódica suelen tener valencias parecidas. ¡Esto te ahorrará mucho tiempo memorizando!

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.
