Salut il me semblerait que l'item B du QCM 14 à la colle du 26/09 serait fausse.

   En effet 18 ne correspondrait-il pas au nombre max d'électrons sur le couche externe et non pas de l'ATOME comme il est écrit dans l'item:

"B.Si n=3, l'atome peut contenir au maximum 18 électrons."

 

Merci pour cette Colle vive le tutorat!
