why does copper show 2 valancies??
Copper exhibits two primary valencies: +1 and +2, which are the most commonly referenced in educational contexts. While the element can also form compounds with higher oxidation states, such as Copper (III) and Copper (IV), these are less frequently discussed. The valence of an element indicates the number of bonds it can form, and in the case of copper, its ability to exhibit multiple valencies is attributed to its electron configuration and the presence of d-orbitals. Understanding these valencies is crucial for interpreting copper's behavior in various chemical reactions.
