Which of these is the correct change observed for the transition metal ion listed upon the addition of small amounts of hydroxide ions or ammonia?

Chromium is the only transition metal to display amphoteric behaviour?

Zn (II) will have how many ammonia groups bonded to it as a complex ion?

+6 is the most stable ion of Chromium.

Copper is the only transition metal for form +1 ions.

Cu (I) is unstable and will undergo disproportionation in solution.

Cu (I) compounds aren't coloured due to it having a full 3d subshell.
