samenvatting basis chemie ( atomen, moleculen, bindingen, reacties,...)

deze samenvatting bevat;
Les 1:
Chemie bestudeert hoe stoffen veranderen.
Zuivere stof = 1 soort deeltje, mengsel = meerdere.
Atoom = protonen, neutronen, elektronen.
Elementen staan in het periodiek systeem volgens atoomnummer.

Les 2:
Atomen willen een volle buitenschil.
Metaal + niet-metaal → ionbinding.
Niet-metalen → covalente binding.
Reactievergelijking: aantal atomen blijft gelijk.

Les 3:
Zuren geven H⁺, basen OH⁻, zouten zijn hun combinatie.
Organische chemie: koolstof vormt ketens → vetten, suikers, eiwitten.
