Bonsoir,

L'ion ammonium NH4+ est un ion positif polyatomique. Expliquer pourquoi.
La NH3 est une molécule qui a crée une liaison avec H en plus. Ce qui a fait perdre l'atome N (et donc a perdu 1 électron).
Comme les électrons sont perdus, ils deviennent alors H+. D'où la positivité polyatomique.
En espérant t'avoir aidé !
