What are the geometric shape and the oxidation number of the copper atom, respectively, for the complex ion,

\left[{Cu}\left({NH}_3\right)_4\left({H}_2 {O}\right)_2\right]^{2+}

View answer and explanation

Correct option: D

Octahedral; + 2

Option D (Octahedral; + 2) is correct because the complex ion has six ligands coordinated to the copper atom, resulting in an octahedral geometry, and the oxidation number of copper is +2.
