Funciones Químicas Inorgánicas Principales
TL;DR
Las funciones químicas inorgánicas agrupan compuestos con propiedades similares debido a su grupo funcional. Entenderlas te permite reconocer, nombrar y formular sustancias inorgánicas usando el estado de oxidación. Las principales funciones inorgánicas son óxido, peróxido, hidróxido, ácido, hidruro y sal.
1. The Mental Model
Think of chemical functions as "families" of compounds. Each family (function) has a specific "feature" (group functional) that makes its members behave similarly, like how all cars generally drive, even if they look different.
2. The Core Material
When we talk about funciones químicas inorgánicas, we're referring to groups of compounds that share very similar chemical properties. This similarity comes from having one or more identical atoms, called the grupo funcional, in their molecular or formula units. The main goal here is to be able to reconocer, nombrar o formular these inorganic substances correctly.
It's super important not to confuse estado de oxidación (EO), número de oxidación, or grado de oxidación with valencia. These terms, while related to how atoms combine, describe different aspects of bonding. The estado de oxidación tells you the charge an atom would have if all its bonds were ionic.
You'll find that in inorganic chemistry, there are five main functions:
* Óxido
* Peróxido
* Hidróxido
* Ácido
* Hidruro
* Sal
Sometimes, special cases pop up. For example, some elements like sulfur (S), selenium (Se), tellurium (Te), fluorine (F), chlorine (Cl), bromine (Br), and iodine (I) have specific rules for assigning their estado de oxidación, especially when forming certain compounds.
Nomenclatura de Iones Monoatómicos
When you're naming single-atom ions (monoatómicos), you always need to put the word "ión" before the name of the chemical species. This applies whether the ion is monoatómico or poliatómico.
Let's visualize the relationship between these core concepts:
