Sarrabm Posted January 8, 2017 Share Posted January 8, 2017 Bonsoir !! Pourquoi le QCM 1 item A est il faux ? Une orbitale 5p est déf par l'ensemble n= 5; l= 2; m= -2,-1 0,1 ou 2 Merci !! Link to comment Share on other sites More sharing options...

Sarrabm Posted January 8, 2017 Author Share Posted January 8, 2017 Donc par exemple pour une orbitale d l peu prendre des valeurs entre 0 et 2 ? Link to comment Share on other sites More sharing options...
caroline01 Posted January 8, 2017 Share Posted January 8, 2017 Pour quelle lettre ? Link to comment Share on other sites More sharing options...
Sarrabm Posted January 8, 2017 Author Share Posted January 8, 2017 Pour une orbitale D Link to comment Share on other sites More sharing options...
caroline01 Posted January 8, 2017 Share Posted January 8, 2017 Oui mais n ? l ou m ? Je vais quand même te donner un exemple : 6d : n = 6 l = 2 m = [-2;2] = -2 -1 0 1 2 Link to comment Share on other sites More sharing options...
Sarrabm Posted January 8, 2017 Author Share Posted January 8, 2017 oui mais L appartient à [0,n-1] d'après le cours Link to comment Share on other sites More sharing options...
Sarrabm Posted January 8, 2017 Author Share Posted January 8, 2017 et donc je me demandais dans ton exemple est ce que L peut aussi prendre les valeurs 0 et 1 avec les m correspondants Link to comment Share on other sites More sharing options...
caroline01 Posted January 8, 2017 Share Posted January 8, 2017 Hoouuu non je ne pense pas... En fait la lettre l est la pour caractériser la forme de ton orbitale : l = 0 → s → une orbitale □. l = 1 → p → trois orbitale □□□. l = 2 → d → cinq orbitale □□□□□. l = 3 → f → sept orbitale □□□□□□□.
