La Tavola Periodica degli Elementi

Hai mai pensato a cosa rende diversi l'oro dal ferro o l'ossigeno dall'idrogeno? La tavola periodica è la risposta a questa domanda! È una tabella che contiene tutti gli elementi chimici scoperti finora.

Questa incredibile invenzione la dobbiamo a Dimitri Mendeleev, uno scienziato russo molto intelligente. Ha organizzato gli elementi in modo geniale: li ha messi in ordine di numero atomico crescente, cioè dal più piccolo al più grande.

La tavola è organizzata come una griglia con sette righe orizzontali chiamate periodi e diciotto colonne verticali dette gruppi. Ogni elemento ha il suo posto speciale con il simbolo (come C per carbonio) e il numero atomico.

Gli elementi sono divisi in quattro grandi famiglie: metalli, non metalli, semimetalli e gas nobili. Alcuni elementi sono anche artificiali, cioè creati dall'uomo in laboratorio!

💡 Curiosità: Ogni quadratino della tavola periodica racconta la storia di un elemento diverso, con le sue caratteristiche uniche!

We thought you’d never ask...

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.
