What is the formula formed by a copper (II) cation and a nitride anion?

Answer 1

Peyton Adams

#3"Cu"^(color(red)(2)+)+"N"^(color(blue)(3)-)rarr"Cu"_color(blue)(3)"N"_color(red)(2)#

The charge of the nitride anion is negative 3, while the charge of the copper(II) cation is positive 2.

It is a synthesis reaction (#A+B=AB#).
