Hoofdstuk 1 Microstructuren
§1 en §2 Atoomopbouw en Periodiek Systeem
Atoomnummer: Aantal Protonen in een element.
Massagetal: Aantal protonen + Aantal Neutronen in een element.
Isotopen: Deeltjes met een verschillen aantal neutronen maar een gelijk aantal protonen.
Massa en lading van de bouwstenen
Protonen: Massa = 14. Lading 1+
Neutronen: Massa = 14, lading 0
Elektronen: Massa 0, landing 1-
Protonen, Neutronen en elektronen
Protonen zijn het atoomnummer (tabel 99) lading per proton is 1+
Neutronen zijn het Massagetal (tabel 25) – het atoomnummer
Elektronen vind je door lading andersom op te tellen
