Salut,

 

Dans le ccb 2018 de chimie de maraichers, au qcm 2 item D on nous dit: "L'atome le plus lourd est le 12C", l'item est faux mais en correction on nous dit "F est l'atome le plus léger". Je comprend pas trop la correction est ce que quelqu'un pourrait m'expliquer svp ?

 

Merci bcp et bon courage ! 💪🏽
