1. Ossidi (Basici e Acidi)
Gli ossidi sono composti binari formati da un elemento e l'Ossigeno (numero di ossidazione -2).
Ossidi Basici (Metallo + Ossigeno)
Si formano quando un metallo reagisce con l'ossigeno.
• Regola: Ossido di + [nome del metallo]. Si usano i prefissi per indicare il numero di atomi.
• Esempio: Fe_2O_3 → Triossido di di-ferro.
