# What is the electron configuration of Cu^+?

Sep 6, 2017

Well we got copper, $Z = 29$.........

#### Explanation:

And thus for the $\text{cuprous ion}$, $C {u}^{+}$, we gots 28 electrons to distribute:

$1 {s}^{2} 2 {s}^{2} 2 {p}^{6} 3 {s}^{2} 3 {p}^{6} 3 {d}^{10}$

And for the $\text{cupric ion}$, $C {u}^{2 +}$, we gots 27 electrons to distribute:

$1 {s}^{2} 2 {s}^{2} 2 {p}^{6} 3 {s}^{2} 3 {p}^{6} 3 {d}^{9}$
