This App teaches both how to find the number of electrons in particles (e.g. atoms, cations or anions). To reinforce what you have learnt in the short notes in this app, there is also a quiz.
Learning how to find the number of electrons is particularly important for the chapter on chemical bonding, such as finding the electronic configuration.
- Drawing dot and cross diagrams (showing all electrons)
- Drawing dot and cross diagrams (showing outermost electrons)
- Quizzes and Tests on Chemical Bonding
