4VWO Chemie Scheikunde samenvatting van H1

1.2 Atoombouw en het periodiek systeem
Atoommodellen door de eeuwen




Elektronenschillen (Bohr) en elektronenconfiguratie




Elektronenconfiguratie = verdeling van de elektronen (e) over de verschillende schillen.
- Max. e in de schil = 2n²
- n = schilnummer (K = 1, L = 2, enzo.)
- Groepen (periodiek systeem): vergelijkbare chemische eigenschappen door het
aantal elektronen in de buitenste schil.

Massagetal en Isotopen




Gemiddelde atoommassa en molecuulmassa berekenen
Gemiddelde atoommassa = het gewogen Mr (molecuulformule) = gem. (atoommassa
gemiddelde van de massa’s van de x aantal atomen) + (enzo.) = ...u
verschillende natuurlijk voorkomende
isotopen van een atoomsoort (in u).
