Question

What Is The Valency of $\mathrm{Cu}$ In ${\mathrm{Cu}}_2{\mathrm{Cl}}_2$?

Answer 1

Valency of $\mathrm{Cu}$ In ${\mathrm{Cu}}_2{\mathrm{Cl}}_2$

• The valency of Copper in ${\mathrm{Cu}}_2{\mathrm{Cl}}_2$ is calculated as follows:
• $0=2\times \mathrm{A}+2\times -1$
• Copper's valency is $\mathrm{A}$, and chlorine's charge is $-1$.
• Therefore,
• $0=2\mathrm{A}+(-2)$
• $$\begin{gathered} \mathrm{A}=\frac{2}{2} \\ =1 \end{gathered}$$

As a result, $\mathrm{Cu}$ in cuprous chloride has a valency of $1$.
